Sažetak
This feature article discusses some selected aspects in the field of vibrational structure calculations
based on vibrational self-consistent field, VSCF, and vibrational configuration interaction, VCI, theory.
As the quality of such calculations depends strongly on the accuracy of the underlying multidimensional
potential energy surface, PES, some techniques will be discussed to establish high-quality
PESs in a fully automated manner. As an alternative to VCI theory multiconfiguration self-consistent
field, VMCSCF, theory and in particular specific aspects concerning the integral evaluation relevant to
both approaches will also be presented. Further aspects concern the efficient calculation of infrared intensities
and Franck-Condon factors in vibronic transitions.(doi: 10.5562/cca2149)
