Near infrared laser spectroscopy of solid parahydrogen: The crystal-field splitting of rovibrational W-1(0) transition
The fine structure of the rovibrational W-1(0) transition (v = 1 <- 0, J = 6 <- 0) of solid parahydrogen has been observed using high-resolution near infrared diode laser spectroscopy. Similar to the case of the pure rotational W-0(0) transition, the W-1 0) transition also exhibits triplet structure which is interpreted as the crystal-field split M components of the J = 6 manifold. The observed splitting is consistent with the theoretical prediction based on the localized J = 6 rotons. The crystal-field splitting parameters obtained by least-squares fitting are in good agreement with the previous work on W-0(0) transition. (C) 2008 Elsevier B. V. All rights reserved.
