Abstract
Assignment of nine hot‐band Q branches in the ν3 (16 μm) region of the diode laser spectrum of UF6, and measurement of their wave number displacements from the origin of the fundamental band, provide values of effective anharmonicity constants x34, x35, and x36. The relationship x3j = −aω0j, where a = (1.28±0.08)×10−3 and ω0j = normal‐mode wave number for j = 4, 5, or 6, has been used to compute spectra in good qualitative agreement with observed spectra between T = 170 K and room temperature.Keywords
