15.
Why are rotational transitions of little use to a spectroscopist?
Because the energy required to induce a rotational transition is so small that it cannot be measured
Because rotational transitions are extremely rare
Because, in liquids and solids, spectral lines corresponding to rotational transitions are broadened as the result of molecular collisions and other interactions
All of the above
Answer: Option
