ShareDoppler-limited spectroscopy at cryogenic temperatures: application of collisional cooling.
Author(s) : NEWNHAM D., BALLARD J., PAGE M.
Type of article: Article
Summary
A coolable gas cell for the measurement of mid-infrared spectra of gases at cryogenic temperatures as low as 77 K is described. Fourier transform infrared spectra of carbon dioxide, nitrogen dioxide, and methyl silane vapours cooled by collisions with helium gas at 77 K are reported. The resulting spectroscopic simplification indicates that efficient collisional cooling of the vibrational, as well as rotational, degrees of freedom occurs.
