Problem
A spectrum obtained for a small organic molecule shows three prominent features:
1. A cluster of very sharp lines centered at 2.0 cm⁻¹.
2. A broad band with several shoulders centered at 1.65 × 10³ cm⁻¹.
3. An intense, relatively narrow band at 4.1 × 10⁴ cm⁻¹.
Which combination of transition types best accounts for these three features, in the order listed above?
(a) Vibrational, rotational, electronic
(b) Rotational, electronic, vibrational
(c) Rotational, vibrational, electronic
(d) Electronic, vibrational, rotational
