The interpretation depends upon the sample's chemical nature, the probe range (Raman shift, cm-1).

Specific vibration modes can be found for organic molecules.

Fingerprint region for organic molecules ranges from 500cm-1 to 2000cm-1.

If low frequency region is probed then crystal characteristics can be investigated as well.

For finding the bond strength: its relatively easier for simple gas molecules like O2, N2 (rotation Raman lines).

But for bigger molecules the picture becomes complex.

There are some specific correlation theories joining Strength-Order to Raman data which may be useful. Refer to paper:

One of the services of the following website is the interpretation of experimental data including Raman spectroscopy

Raman Data Interpretation is an art like other characterizations and requires a lot of background knowledge. Please watch this video and I feel this video can clear all your doubts regarding raman spectroscopy.
