Technoplast Packaging Interview Questions and Answers

CO2 is IR active. IR region ranges from 4000-400 cm-1. Esters have a peak in the 1750-1735 cm-1 region.

• CO2 has a linear structure and has a dipole moment, making it IR active

• IR region is divided into three regions: near-IR, mid-IR, and far-IR

• CO2 absorbs IR radiation in the mid-IR region, specifically around 2349 cm-1

• Esters have a peak in the carbonyl stretching region, which is around 1750-1735 cm-1
