The rotation and inversion of normal and deuterated ammonia in inert matrices

摘要: Abstract Infrared spectra have been recorded for all of the vibrational fundamental regions NH 3 in argon, krypton, and xenon matrices, ν 2 region neon nitrogen , ′ 4 ″ deuterated ammonias an argon matrix. Detailed studies temperature time dependence absorptions attributed to rotational structure transitions led assignment consistent with almost free rotation ammonia molecule rare gas matrices. The theory Devonshire has used evaluate a barrier these inversion splittings observed fundamentals D, NHD are somewhat smaller than gas-phase molecules, but calculated potential is increased by only about 10% gases. No spectral can be or -d n However, its C axis may occur
