Question 1

The force constant of HCl is 480 N/m. If the atomic masses are 1 u and 35 u (1 u = 1.66 × 1027 kg), find the fundamental frequency (in Hz).

6.4 × 1013

9.2 × 1013

7.7 × 1013

8.7 × 1013

1.4 × 1013


Question 2

The frequency of a microwave absorbed by a molecule when changing from the J = 3 to J = 4 rotation energy state is 4.61 × 1011 Hz. The moment of inertia of the molecule (in kg m2) is

5.70 × 1045

1.45 × 1046

1.12 × 1044

2.91 × 1046
