Weobtained five sets of spectroscopic parameters. The Darling-Dennison interactionbetween 2ν4and 2ν5, which was demonstrated to be important in the analysis of thepure bending states, was also considered between the same levels associated with thevarious stretching states.The standard deviation for each global fit was smaller than 0.001 cm −1 .
