The Raman Spectrum of Deuterium [PDF]

open access: yesThe Journal of Chemical Physics, 1935
A number of observers have studied the emission spectra of mixtures of hydrogen and deuterium. The Fulcher bands of HD and D2 have been photographed [1]. In the extreme untrlaviolet Jeppesen [2], and Beutler and Mie [3], have obtained emission spectra from hydrogen-deuterium mixtures and have ascribed several bands to HD.

Raman Spectrum of Diamond [PDF]

open access: yesNature, 1930
In the course of an examination of the infra-red and ultra-violet regions of the spectrum of a large number of diamonds, we have come across one which, unlike the others, is transparent both at about 8μ, and also in the ultra-violet so far out as λ2300.
