Аннотация

A careful rotational analysis of the ground vibrational state of the CHD₃ molecule is made on the basis of the ground state combination differences method using, as the initial information, transitions from 12 infrared absorption bands: ν₃(A₁), ν₆(E), ν₅(E), 2ν₃(A₁), 2ν₆(A₁), 2ν₆(E), ν₃ + ν₆(E), 2ν₅(A₁), 2ν₅(E), ν₃ + ν₅(E), ν₅ + ν₆(A₁ + A₂), and ν₅ + ν₆(E). More than 2500 "forbidden" transitions were used to determine the parameters C, D_K, and H_K. a₁ - a₂ (K = 3) splittings in the ground vibrational state were found and analyzed.
