Compute the IR Active Vibrational Modes Are Present in The Molecule Chemistry Ques

Question Description

I’m working on a chemistry multi-part question and need guidance to help me learn.

In the molecule of OCS, the fundamental frequency of the C=O vibration is 1750 cm-1.

1. Calculate the force constant of the CO bond (in N/m).                       

2. How many IR-active vibrational modes are present in the molecule?
