A New Sensitive Detection Scheme for Helium Nanodroplet Isolation Spectroscopy: Application to Benzene

Marcel Drabbels, Evgeniy Loginov, Andreas Braun

A new method is presented for recording excitation spectra of molecules embedded in helium nanodroplets. The method relies on the complete evaporation of the droplets following excitation of an dissolved molecule and the subsequent detection of the remaini ...

Direct Observation of Microscopic Solvation at the Surface of Clusters by Ultrafast Photoelectron Imaging

Majed Chergui, Alejandro Gonzalez Gonzalez

We report on microscopic observation of solvation by argon atoms of excited states of an ethylenic-like mol., TDMAE (tetrakis dimethylaminoethylene). Two exptl. methods were used: gas phase dynamics for the observation of the evolution through excited stat ...

Quantum calculations on the acid catalyzed rearrangements of norborn-5-en-2-one, 7-oxanorborn-5-en-2-one and 7-azanorborn-5-en-2-one - The electron-releasing effect of homoconjugated carbonyl group

Pierre Vogel, Samuele Giani

Protonation of norbom-5-en-2-one gives 6-oxo-2-norbomyl cation (2) as most stable C7H9O+ cation. Quantum calculations at B3LYP/6-31G(d) level (gas phase, 1 atm, 25 degrees C) predict a C-s-structure for 2 that can be represented as an intramolecular pi-com ...
