TL;DR: The ExoMol database as mentioned in this paper provides extensive line lists of molecular transitions which are valid over extended temperature ranges, including lifetimes of individual states, temperature-dependent cooling functions, Lande g-factors, partition functions, cross sections, k-coefficients and transition dipoles with phase relations.
Journal ArticleDOI
A variationally computed T = 300 K line list for NH3.
TL;DR: Comparisons suggest that HITRAN is missing significant ammonia absorptions, particularly in the near-infrared, and a new accurate ab initio dipole moment surface is determined at the frozen core CCSD(T)/aug-cc-pVQZ level.
Journal ArticleDOI
Automatic differentiation method for numerical construction of the rotational-vibrational Hamiltonian as a power series in the curvilinear internal coordinates using the Eckart frame
TL;DR: The results show that very high accuracy and quick convergence can be achieved even with moderate expansions if curvilinear coordinates are employed, which is important for applications involving large polyatomic molecules.
Journal ArticleDOI
ExoMol line lists – VIII. A variationally computed line list for hot formaldehyde
TL;DR: In this article, an empirical potential energy and ab initio dipole moment surfaces are used as the input to the nuclear motion program TROVE, which contains 10.3 million rotational-vibrational states and around 10 billion transition frequencies.
Journal ArticleDOI
Detecting Chirality in Molecules by Linearly Polarized Laser Fields.
TL;DR: A new scheme for enantiomer differentiation of chiral molecules using a pair of linearly polarized intense ultrashort laser pulses with skewed mutual polarization is presented, able to excite a coherent unidirectional rotation of two enantiomers with a π phase difference in the molecular electric dipole moment.
