Abstract
The high resolution spectrum of the fundamental band of deuterium impurity embedded in solid parahydrogen has been studied using a difference frequency laser spectrometer. This observation represents the first case of high resolution matrix spectroscopy in solid hydrogen. Both the Q1←0(0) and Q1←0(1) transitions were resolved into sharp features with a typical linewidth of ≲ 10 MHz, while both the S1←0(0) and S1←0(1) transitions appeared to be much broader with widths of ∼0.07 cm−1. A discussion of the linewidths based on homogeneous broadening is presented.Keywords
