1. The equilibrium internuclear distance of deuterium iodide, DI, is 160.4 pm, where 1 pm = 1x10-12m.The relevant atomic masses are: mD = 2 amu and mI = 127 amu,where 1 amu = 1.661 x10-27kg.
b. )At what line positions, in wavenumbers (cm-1), would you observe the first three transitions in the R branch (?J = +1) in an infrared absorption spectrum of DI, corresponding to the transition v = 0 ? 1? Assume that DI behaves as a rigid rotator/harmonic oscillator with ?= 1637cm-1.
