NiH2 has a singlet ground state
Contrary to previous ab initio and semi-empirical studies, density functional theory and high level ab initio calculations predict that the ground state of NiH2 is a bent singlet state. The linear tri...

Nucleic acid base anions play an important role in radiation-induced mutagenesis. Recently, it has been shown that isolated (gas-phase) nucleobases form an exotic form of negative ions, namely, dipole...

Recent theoretical predictions of anisotropy-induced polarization components in the signal wave generated from gas-phase degenerate four-wave mixing spectroscopy are verified experimentally by probing optically pumped ensembles of jet-cooled molecules that are characterized by well-defined orientation and/or alignment parameters. Aside from corroborating recent multipole moment analyses, detailed simulation of recorded data sets demonstrates the feasibility of performing a new class of resonant four-wave mixing measurements designed to extract angular momentum anisotropy information from target species in a manner that is both background-free and insensitive to isotropic contributions. ©1998 American Institute of Physics.
