Molecular Spectroscopy
Exam-focused revision notes on Molecular Spectroscopy for CSIR-NET Chemical Sciences, GATE Chemistry and IIT-JAM — the core concepts, the formulas worth memorising, the traps that cost marks, and a quick-recall table.
The core idea — regions & what they probe
Different regions of the electromagnetic spectrum excite different kinds of molecular motion. Higher energy means shorter wavelength and a larger transition.
