You measure the vibrational-rotational spectrum of HCl. The estimated separation between absorption peaks is Îf â 5.5 x 10^11 Hz. The central frequency of the band is fo = 9.0 X 10^13Hz. Required:
a. What is the moment of inertia?
b. What is the energy of vibration for the molecule?

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.
