Infrared spectra of high polymers : Part IX. Polyethylene terephthalate
(Elsevier, 1959)
Infrared spectra of polyethylene terephthalate and three of its deuterated analogs have been obtained in the region of 70 to 3600 cm-1, polarized spectra having been obtained down to 330 cm-1. On the basis of analysis of ...
Selection rules for the vibrational spectra of high polymers
(Elsevier, 1957)
With the aid of the Born cyclic postulate, the selection rules for the vibrational modes of a crystalline polymer and an oriented infinite chain-molecule have been discussed. The necessary conditions for the modes to be ...
Rotation spectrum of methyl alcohol
(Elsevier, 1959)
The rotation spectrum of methanol vapor has been measured from 50 to 457 cm-1. Combining these data with the work of Borden and Barker provides an accurate map of the spectrum to 625 cm-1 together with some provisional ...
Electric field induced vibration rotation spectrum of H2 and D2
(Elsevier, 1959)
Electric field induced absorption has been observed for some 8 vibration-rotation transitions of H2 and for 7 of D2. An alternating electric field was used to modulate the transmitted intensity. Percentage absorptions as ...
