Gaseous HBr has an absorption band centered at about

Please show how to solve this questions.1. Gaseous HBr has an absorption band centered at about 2645/cm consisting of a series of line approximately equally spaced with an interval of 16.9/cm. For gaseous DBr estimate the frequency in wave number of the band center and the interval between lines.Answer 18 828.56 /cm2. The roational Raman spectrum of nitrogen gas shows Raman shift of 19, 27, 34, 53,…./cm , corresponding to rotational quantum number of the initial state of J=1, 2, 3, 4,……Since the spacing is 4Be, ignoring centrifugal distortion, what is ReAnswer : 112.6 pm
