TROVE [Theoretical RO-Vibrational Energies] is a variational package for the first-principles calculations of ro-vibrational energy levels and spectra of small polyatomic molecules. The philosophy behind TROVE is to provide black-box methods covering many important aspects of rovibrational spectroscopy, from super-accurate energy levels and complete spectroscopic line lists for elevated temperatures to quantum nuclear dynamics in the presence of external electromagnetic fields.
The workshop is addressed to developers of TROVE, and it is intended to bring together TROVE and closely related program contributors and potential TROVE “customers” to provide a forum for focused discussion on new research topics and trends and relevant theory/program development, as well as to foster active discussion on some issues related to TROVE project organisation and code dissemination.
