Calculated structures and microwave frequencies of HNSi and HSiN.
Abstract
Ab initio calculations on the species HNSi and HSiN, including configuration interaction, have shown that HNSi is the more stable isomer by approximately 300 kJ/mol. The microwave spectra of both species including quadrupole structure have been predicted and are shown to be inconsistent with interstellar emission lines which have been tentatively attributed to HSiN.
