[Pw_forum] How to identify different types of normal modes in example 15 for RAMMAN and IR Spectroscopy ?

[Naseem Hassan]

Dear Members

I have a no experience with experimental spectroscopic techniques. Kindly
guide, *How to identify/read different types of normal modes (bending,
**symmetric
stretching, **symmetric stretching etc.) in example 15 for RAMMAN and IR
Spectroscopy.*

The text is mentioned below indicating different modes.

Example#15 (ph.x)
"The obtained results for CO2 show normal modes at 604.82 (bending),
1362.90 (symmetric stretching) and 2441.15 cm-1 (antisymmetric stretching)"

Best Regards
Naseem
