Abstract
We report measurements of infrared transitions of HD and $D_{2}$ impurities ($\sim 1-2\%$) in a parahydrogen sample of 0.7 cm long at 4.2 K. Spectra from 1800 to 8000 cm-1 recorded by a Bomem FTIR spectrometer show the double transitions between a p-H2 and an impurity molecule and also the single transitions of impurity molecules. The sharpness of the latter indicates the possibility of accurate measurement of linewidth and line position of transitions of HD and $D_{2}$ using laser spectroscopy.
