Abstract: Apparatus integrating a Fourier transform-infrared (FT-IR) spectrometer and a mid-infrared difference frequency generation (DFG) laser pectrometer was built for the study of the matrix isolation spectrumin solid molecular hydrogen. A 3-cm-long molecular hydrogen crystal was grown in a liquid-helium Dewar and its infrared absorption spectrum in the 1-5 μm region was recorded to test the system. The W0(0) (v=0→0, J=6→0) line around 2410 cm-1 of solid hydrogen was investigated with the DFG laser spectroscopy. High-resolution matrix isolation spectrum of CO2 co-deposited with hydrogen on a BaF2 cold plate at liquid-heliumtemperature was studied.

Key words: Hydrogen molecule, Matrix isolation, Fourier transform-infrared spectroscopy, Laser difference frequency generation, Carbon dioxide
