High-Resolution Infrared Spectroscopy of Solid Hydrogen: The Tetrahexacontapole-Induced ΔJ=6 Transitions

Abstract

Weak new features in the absorption spectrum of solid hydrogen were observed by high-resolution infrared spectroscopy, and assigned as transitions with total change in angular momentum of ΔJ=6. The tetrahexacontapole (64-pole)-induced rotational transition W_0(0) was studied with a difference frequency laser spectrometer and found to be very narrow, with a linewidth of 0.003 cm^-1 HWHM in 99.8% parahydrogen. Frequencies, linewidths, and integrated absorption strengths were measured for several pure rotational and rotation-vibration transitions from 1800 to 7000 cm^-1, and the tetrahexacontapole moment was determined.
