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

Category : Alkaloids Hydrogen Bonding Microsolvation New Results! Non-covalent Interactions Publications

The dimer sparteine-water has been highlighted as cover of PCCP and part of “2017 PCCP HOT Articles“. Sparteine is a tetracyclic quinolizidine 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 used in metal complexation. Kinetic reasons explain that the cluster retains the monomer trans conformation.

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

Cotinine in Chemistry News

Category : Molecular Structure New Results! Nicotinoids Publications

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.

Below the note in ChemistryViews…
