Abstract

Spectra of the $NH_{3}$ bands at $950 cm^{-1}$ and $3300 cm^{-1}$ have been obtained at reduced temperatures with cells cooled with liquid nitrogen to approximately $190^{\circ}K$. Data were obtained for optical thicknesses between 0.1 atmos-cm and 4 atmos-cm and total pressures between 10 and 1000 torr. The nature of the observed temperature dependence is discussed.
