Rovibrational matrix elements of the quadrupole moment of N2 in a solid parahydrogen matrix

Multiplet splittings and intensities of fine structure components of the Q1(0)H2 + S0(0)N2 transition in a solid parahydrogen matrix

A comprehensive analysis of theoretical multiplet splittings and intensities of the fine structure components of the Q(1)(0)H(2) + S(0)(0)N(2) transition in a solid parahydrogen crystal is presented. The consideration of higher order anisotropic term responsible for splittings is essential to explain the observed splitting of the three components. The pair interaction parameters DeltaB and DeltaC have been determined by comparing the theoretical splittings with the experimental values. The information about the small splittings (approximately 0.1 cm(-1)) due to crystal-field interaction is completely obscured due to fast hopping of v(') = 1, J(') = 0 H(2) vibron. Also, the theoretical expressions are derived for the intensities of the fine structure components of the Q(v(H(2)))(0) + S(v(N(2)))(0) transition and the theoretical results are compared with the experimental findings.
