✦ Synopsis

We report a theoretical and experimental investigation of the dynamical Stark effect in a tetrahedral molecule, silane (SiH(4)). We use a tetrahedral formalism and Floquet theory to calculate the absorption spectra for the molecule dressed by an intense nonresonant pulsed laser. Experimentally, the dynamical Stark effect is observed for transitions of the nu(2)/nu(4) vibrational polyad of SiH(4) by means of nanosecond diode laser absorption spectroscopy and a Nd:YAG laser excitation.

The dipole moment parameters \(\mu_{0}\) and \(\mu_{33}\) of \(\mathrm{SiF}_{4}\) have been determined previously from linear Stark effect observations on \(E\)-type transitions. These dipole moment parameters have been used to predict the nonlinear Stark effect which arises from interactions betwee

We measured absolute line intensities in two bands of 12 C 2 H 2 near 7.5 m, namely the 4 ϩ 5 (⌺ u ϩ )-0(⌺ g ϩ ) and 4 ϩ 5 (⌬ u )-0(⌺ g ϩ ) bands, using Fourier transform spectroscopy with an accuracy estimated to be better than 2%. Using theoretical predictions from Watson [J. K. G. Watson, J. Mol.
