Abstract
“The infrared, absorption of the fundamental vibration rotation band of $H_{2}$ induced by an applied electric field was first observed by Crawford and $Dagg^{1}$. By a slightly different method, we have measured the frequencies and intensities of several lines in the Q and S branches of both $H_{2}$ and $D_{2}$. The absorption produced by an alternating electric field of strengths up to 100,000 volts per cm, was analyzed with a grating spectrometer and was synchronously detected. Absorptions as small as I part in 50,000 at a resolution of $1 cm^{-1}$ could be detected.”
