 Title: INFRARED INTENSITIES OF THE FUNDAMENTAL FREQUENCIES OF SILANE Creators: King, W. T.; Levin, Ira W. Issue Date: 1960 Abstract: “Absolute intensity measurements have been made on the infrared active fundamentals of $SiH_{4}$ and the two non-overlapped fundamentals of $SiD_{2} H$ at $2182 cm^{-1}$ and $851 cm^{-1}$. The absorption bands were pressure broadened with nitrogen or helium up to total cell pressures of about 70 atmos,. and the intensities -were determined by the method of Wilson and $Wells,^{1}$ except that the observed optical density was integrated Against log $\nu$ instead of $\nu$. From Meal and $Wilson’s^{2}$ assignments, approximate harmonic fundamental frequencies were estimated and normal coordinates-computed. Using these normal coordinates, derivatives of the dipole moment with respect to internal symmetry coordinate were found that reproduced the measured intensities within the estimated experimental error. Additional intensity measurements are being carried out on $SiD_{4}$.” URI: http://hdl.handle.net/1811/7949 Other Identifiers: 1960-F-1
