Question

IR spectroscopy

• A. has useful range of radiation from 2.5 to 15 microns
• B. uses Bolo meter as one of the detectors
• C. is unsuitable for analysis of organic gases
• D. is unsuitable for analysis of mixture of metals

Hint:

Bolometers are commonly used thermal detectors in infrared spectroscopy setups.

Answer 1

The Correct Option is B

A bolometer is a sensitive thermal detector used in IR spectroscopy to detect infrared radiation by measuring temperature changes. IR spectroscopy is suitable for analyzing organic compounds, as they absorb IR radiation at characteristic frequencies.
