A. Given the force constants for N₂ and O₂ are 2287 and 1133 N/m, respectively, calculate their vibrational wave numbers.

            For N₂ the wave number = _________________.

            For O₂ the wave number = _________________.

B. Calculate the infrared absorption intensity of the v=0 à v=1 transition of O₂.

Infrared absorption intensity for oxygen = ______________________.
