The Calculation of Ro-Vibrational Spectra Using Supercomputers
TL;DR: Developments in the use of supercomputers for the generation of first principles, synthetic, ro-vibrational spectra for triatomic molecules, and a previously published two-step procedure for calculating rotationally excited states are discussed.

TL;DR: In this article, the measured active rotational vibration energy levels (MEVLE) were determined for the ground electronic state using the Measured Active Rotational-Vibrational Energy Levels (Marvel) technique.
Journal ArticleDOI
Theoretical rovibronic spectroscopy of the calcium monohydroxide radical (CaOH).
Alec Owens,Victoria H. J. Clark,Alexander O. Mitrushchenkov,Sergei N. Yurchenko,Jonathan Tennyson +4 more
TL;DR: In this article, a high-level ab initio theory and variational nuclear motion calculations were used to construct potential energy surfaces (PESs) for the X2Σ+ and A2Π electronic states along with A-X transition dipole moment surfaces (DMSs).
Journal ArticleDOI
Quantum mechanics gets real
TL;DR: The fundamental aspects of non-relativistic quantum mechanics have remained essentially unchanged ever since, physics and chemistry have been driven largely by experiment as discussed by the authors, and the difficulty is only that the exact application of these laws leads to equations much too complicated to be soluble.
Journal ArticleDOI
Theoretical study of the low-energy electron-collision cross sections of isomers HOOCl, HOClO and HClOO in gas phase
TL;DR: In this article, a systematic study considering basis set, polarisation and the Born closure technique is performed, and cross sections for the elastic electron scattering by HOOCl, HOClO and HClOO isomers are calculated using the R-matrix method.
