Answer 1

Answer:

The correct answer is : (a) $E_e_l_e > E_v_i_b > E_r_o_t$

Explanation:

• The investigation of electromagnetic (EM) radiation's interactions with matter is known as molecular spectroscopy.
• Its foundation is the examination of electromagnetic radiation that is emitted, absorbed, or scattered :

1. Chemical evaluation (finding a chemical fingerprint, so to speak).
2. Molecular composition (bond lengths, angles, strengths, energy levels, etc...).

Molecular energy can be held as either potential or kinetic energy in a number of different ways, such as:

Rotational energy :

• Rotational energy is the kinetic energy involved in the molecule-tumbling motion. This has a quantization.

Vibrational energy :

• Atoms or groups inside molecules oscillate, creating vibrational energy (potential energy kinetic energy exchange). This has a quantization.

Electronic energy :

• Energy that is stored as potential energy in excited electronic structures is known as electronic energy. This has a quantization.

A series of molecular energy levels are produced as a result. The measurement of level transitions is referred to as spectroscopy.
