Answer 2

Fingerprint region is present in Infrared Spectroscopy (IR spectroscopy) which shows all the regions of bending vibrations.

Explanation:

Infrared spectroscopy is the process in which an infrared sadiation interact with the matter.Fingerprint region in infrared spectroscopy are use to indentify the presence of unknown or two different organic compunds.

There are several significance of fingerprint region such as:

1. Fingerprint regions are majorly used in authentication systemsthat acquires image of finger and processed as automated fingerprint authentication system.
2. It is also used in forensic laboratories where different techniques are use to obtain fingerprint region including ninhydrin, diazafluorenone and vacuum metal deposition.
3. It has advantages in crime investigation where the fingerprints are retrieved using developers and further processed using DNA profiling,
4. Detection of fingerprint region helps in drug detection as well for example fingerprint of tobacco smokers contain nicotine.
