Question – (1) - One
of the modern methods of studying free radical is –
Options – (A) IR spectra
(B) UV spectra
(C) CIDNP
(D) Microwave
spectra
Answer with
explanation –
The free radicals can be detected by Magnetic method, Electron
Spin Resonance Spectroscopy (ESR), and Chemically Induced Dynamic Nuclear Polarization
(CIDNP).
Therefore, the answer is (C) CIDNP - Chemically Induced
Dynamic Nuclear Polarization (CIDNP).
