Abstract:
Molecules have different energy states: electronic,
vibrational, rotational, and nuclear. Quantized energy
is responsible for each transition (e.g., rotational -
microwaves, infrared - vibrational) within the molecule.
UV-visible spectroscopy is one of the principle analytical
tools used by chemists to find out absorption properties
of molecules in ultraviolet (200 - 400 nm) and visible (400
- 700 nm) regions of the electromagnetic (EM) spectrum
