The v = 0 to 1 vibration-rotation spectrum of a diatomic molecule exhibits transitions for R(0), R(1), P(1) and P(2) lines at 2241, 2254, 2216 and 2203 cm–1, respectively. From this data, we can conclude that the molecule
1
has rigid rotation and harmonic vibration
2
has anharmonic vibration
3
has rotational-vibrational interaction
4
is affected by nuclear spin-statistics
5
