Abstract
The linestrengths, self-pressure broadening and shifting coefficients have been measured for P3 (10)- R3 (12) lines in the second overtone band of hydrogen iodide. A dipole moment function in terms of the reduced nuclear displacement x = (R â Re)/Re is obtained using rotationless dipole matrix elements determined by the Herman-Wallis analysis of the (1, 2, 3 â 0) HI bands: μ (x) = 0.4471(5) â 0.0770(2)x + 0.547(3)x2 â 1.93(2)x3, in a full agreement with the function proposed previously [J. Mol. Spectrosc. 223 (2004) 67]. A close match is demonstrated of the results of most recent relativistic calculations [Phys. Chem. Chem. Phys. 6 (2004) 3779] with the spectroscopically derived electric dipole parameters for HI. Line-mixing in the band head is observed, the self-pressure shifting and broadening coefficients for the (3 â 0) band lines are determined.
