The Infra‐Red Absorption Spectra of Ethylene and Tetra‐Deutero‐Ethylene under High Resolution
(The American Institute of Physics, 1942-02)
The fine structure of several infra‐red absorption bands of C2H4 and C2D4 have been resolved. From the rotational constants so found, the C☒C and C☒H distances in this molecule were calculated to be 1.353 and 1.071A, and ...
The Infra‐Red Absorption Spectrum of Mono‐Deutero‐Ethane under High Resolution
(The American Institute of Physics, 1949-02)
The infra‐red spectrum of C2H5D has been investigated under high resolution. As expected, the bands corresponding to degenerate vibrations of C2H6 are split into two components with oscillations in the symmetry plane and ...
The Infra‐Red Absorption Spectrum of Methyl Amine
(The American Institute of Physics, 1940-03)
The parallel type methyl amine band at 10μ has been resolved. Its center is at 1045.27 cm—1, and the very regular structure of its P and R branches indicates a close approximation to axial symmetry. The mean of the two ...
The Infra‐Red Absorption Spectrum of Propane
(The American Institute of Physics, 1941-07)
Of the twenty‐seven internal degrees of freedom of propane, all nondegenerate, twenty‐two may appear as fundamental absorption bands. These bands fall into three symmetry classes, designated A1, B1 and B2, and distinguishable ...
