When a molecule absorbs ir eletromagnetic energy, what are the vibrational modes affected?

Stretching vibration and bending vibration

Explanation:

1. Stretching vibration results in the variation of the bond length. There are two types of stretching vibration:

2. Bending vibration results in the variation of the bond angle.

These can be grouped into 4 types:

truck y has a greater velocity than truck x.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
