The carbon suboxide (C3O2) interactions with amorphous or crystalline ice surfaces in high vacuum are studied using temperature-programmed desorption (TPD) monitored by Fourier transform infrared spectroscopy (FTIR). We show clearly that unlike with

Ab initio calculation of vibrational force fields: Determination of non-redundant symmetry coordinates by least-square component analysis

Autor: A. Allouche, J. Pourcin

Publikováno v: Spectrochimica Acta Part A: Molecular Spectroscopy. 49:571-580

A general procedure is described for vibrational analysis, using an ab initio force constant matrix which is transformed into the generalized valence force field. A method using numerical least-square fitting and redundancy elimination is proposed to
