Caminati Festschrift

Category : General News , Group News

Jens-Uwe Grabow, Alberto Lesarri and Sonia Melandri acted as Guest Editors of two special volumes of the Journal of Molecular Spectroscopy dedicated to honour Prof. Walther Caminati on his retirement, with the title “Spectroscopy and inter/intramolecular dynamics in honor of Walther Caminati
Walther”. Prof. Caminati is one of the most important contributors to the development of rotational spectroscopy worldwide, publishing more than 400 articles in his career, with particular attention to molecules and molecular complexes presenting large amplitude internal dynamics.

In the picture issues 335 and 337 of the Journal of Molecular Spectroscopy and Prof. Caminati.

Kisiel visit

Category : Group News

Prof. Dr. Zbigniew Kisiel, a leading figure in rotational spectroscopy and researcher of the Institute of Physics of the Polish Academy of Sciences, visited the UVa in May, 8-19, 2017. Prof. Kisiel was invited by the UVa Doctoral School to give the course “Analysis of broadband rotational spectra” which was attended by several Ph.D. students, Postdocs and interested staff of the Department. Prof. Kisiel mantains the useful web site “Programs for Rotational Spectroscopy“.

A picture of Prof. Kisiel in our lab is shown below.

Fair of Science

Category : General News

The Fair of Sustainable Science was organized last May 6 by the UVa, the Scientific Park and the City of Valladolid. The Fair intends to communicate Science to the general public, and included different activities and stands of several schools, research groups and companies.

Below the ecologic motor presented by the students of the “Antonio Tovar” High School:

Sparteine in PCCP

The dimer sparteine-water has been published in PCCP. Sparteine is a tetracyclic quinilizidine alkaloid used in assymetric synthesis, with two trans and cis conformations. We investigated whether addition of a water molecule flips the molecule by formation of a double hydrogen bond to the cis diamine. However, kinetic reasons explain that the cluster retains the monomer trans conformation.

In the picture below the conversion between the observed trans isomer (above) and the alternative cis isomer (below).

Cotinine in Chemistry News

A work on the nicotinoid cotinine in collaboration with Emilio Cocinero in Bilbao has been highlighted in ChemistryViews (the electronic Chemistry magazine by Wiley and ChemPubSoc) and the Cover of Chemistry: A European Journal. The manuscript presents a rotational investigation of cotinine, where two conformations were found and compared to nicotine.

March for Science

Category : General News

The federation of Spanish scientific societies (COSCE) is promoting the “Manifest for Science 2017“, asking for  a coherent and permanent impulse to Science in Spain. The document can be signed on-line. This initiative is coincident with the global “March for Science” organized worldwide last April, 22, and near simultaneous with the discussion of the Spanish national budget, where scientific funding will decrease (again) by ca. 2.64% in 2017 according to COSCE. The funding cuts in Science accumulate more than 30% in recent years. Choose your option: 1) There is no future for Science in Spain; 2) We are so smart that we can work without budget. 3) No problem because we have very good football teams.

You can see below a picture of our lab taken from a satellite:

Prague meeting 2016

Category : Conferences

Prof. Stepan Urban and his group at the University of Chemistry and Technology of Prague (VSCHT) organized the 2016 edition of the International Conference on High Resolution Molecular Spectroscopy from August 30 to September 3, 2016. Plenary talks included contributions from Cristobal Pérez (now in Schnell‘s group at Hamburg), José L. Alonso and Tim Zwier. The special Ioannes Marcus Marci Session was given by Prof. Richard N. Zare. The next Conference will be organized jointly by the University of Valladolid and the University of Basque country in Bilbao in 2018, with Alberto Lesarri and Emilio J. Cocinero as chairmen.

Below a view of Prague and the entrance to the University of Chemistry and Technology.

China visit

Category : Group News

A new microwave Spectroscopy group has been created at the University of Chongqing by two chinese researchers at the School of Chemistry and Chemical Engeering, Qian Gou and Gang Feng. Alberto Lesarri and Jens-Uwe Grabow were invited to visit the lab  in the wonderful Huxi campus in Chongqing last August for the first operations of the new spectrometer. The University of Chongqing was founded in 1929 and comprises 4 campus. Alberto gave a talk reviewing the applications of rotational Spectroscopy to structural Chemistry (August 5th) and a seminar on spectroscopic software tools (August 8th). Excellent hospitality in Chongqing and great future for Spectroscopy in China.

Enflurane published

The conformational landscape of enflurane was published in Chemistry – A European Journal. This report closes a series or rotational investigations on volatile and injection anesthetics, including among others sevoflurane, isoflurane and propofol. Enflurane has three distinct rotamers in the gas phase, originated by the internal rotation of the terminal chlorine atom. The presence of hyperfine interations and different isotopologues resulted in a crowded spectrum, as can be observed in the figure below.figure-ethrane-web
