This book introduces the factorization method in quantum mechanics at an advanced level,
with the aim of putting mathematical and physical concepts and techniques like the …

The sudden removal of an inner shell electron from a molecule by photoionization generally
leads to the production of vibrationally excited cationic states. Recent experimental results …

Despite more than 200 years of sulfur research the chemistry of elemental sulfur and sulfur-
rich compounds is still full of “white spots” which have to be filled in with solid knowledge …

Cavity ring-down polarimetry (CRDP), a new, ultrasensitive method for probing circular
birefringence and circular dichroism, has been developed by extending the well-established …

Photoionization mass spectrometry using tunable vacuum-ultraviolet synchrotron radiation is
applied to the study of C3H2 sampled from a rich cyclopentene flame. The photoionization …

A new method of Franck–Condon (FC) factor calculation for nonlinear polyatomics, which
includes anharmonicity and Duschinsky rotation, is reported. Watson's Hamiltonian is …

An efficient new procedure for calculating Franck–Condon factors, based on the direct
solution of an appropriate set of simultaneous equations, is presented. Both Duschinsky …

Normal mode coordinates of vibrational states associated with one electronic state are
generally different from those of vibrational states associated with other electronic states in …

We present an extension of the Hamiltonian of the two dimensional limit of the vibron model
to encompass all possible interactions up to four-body operators. We apply this Hamiltonian …

Sulfur is the element with the largest number of binary oxides. In this chapter the lower sulfur
oxides are reviewed most of which contain more sulfur than oxygen atoms per molecule and …
