Abstract
The pure rotational Raman spectra of s-triazine (C3H3N3) and s-triazine-d3 (C3D3N3) vapor were photographed in the second order of a 21-ft. grating spectrograph. The rotational constants were found to be B0(C3D3N3) = 0.21460 ± 0.00008 cm−1 and B0(C3D3N3) = 0.19358 ± 0.00015 cm−1. These values, together with the assumption that the molecule is planar and has a CH bond length of 1.084 Å, give the following values for the structural parameters: r0(CN) = 1.338 ± 0.001 Å, [ ]NCN = 127°, and [ ]CNC = 113°.Keywords
