Ans-: Difference between IR and UV Spectrum.
|
IR Spectrum |
UV Spectrum |
|
1. IR radiation is used,
which causes bending and stretching vibrations in organic compounds. |
UV radiation
is used for getting UV spectrum. Electronic excitation takes place. |
|
2. The IR spectra are usually
expressed in terms of frequency in wave number units. |
The UV
spectra are generally expressed in terms of wavelength in nm units. |
|
3. It helps especially in
identifying the functional group of the organic compound. |
It helps in
confirming the presence of conjugated system and/or carbonyl group in the
organic compound. |
|
4. It is possible to
differentiate inter- and intra-molecular hydrogen-bonding by using IR
spectrum. |
Not
possible. |
