Spectroscopic study of phosphine-substituted oligothiophenes
Article Abstract:
The spectroscopic behavior of a series of mono-(diphenylphosphino) and bis-(diphenylphosphino) alpha-substituted oligothiophenes varying in length is described. Density functional calculations show that the contributions of the P lone pair to the highest occupied molecular orbital diminishes as the oligomer length increases.

Excited state and ground state proton transfer rates of 3-Hydroxyflavone and its derivatives studied by Shpol'skii spectroscopy: the influence of redistribution of electron density
Article Abstract:
The mechanisms of excited-state intramolecular proton transfer (ESIPT) and ground-state back proton transfer (BPT) in 3-hydroxyflavone (3HF) at cryogenic temperatures are studied. The influence of redistribution of electron density is studied with the help of ShpolEskii spectroscopy.
