1.	Which of the following is not used as pyroelectric material used in pyroelectric transducers in Infrared spectroscopy?(a) Triglycine Sulphate(b) Deutrated Triglycine Sulphate(c) Some Polymers(d) Tetraglycine sulphateThis question was addressed to me in a job interview.The above asked question is from Instrumentation of IR topic in chapter Colorimetry and Spectrometry of Analytical Instrumentation
Answer» CORRECT choice is (d) Tetraglycine SULPHATE To explain I would say: Pyroelectric materials are deutrated triglycine sulphate, triglycine sulphate and some POLYMERS. They give RISE to potential when SUBJECTED to a heating or cooling effect.
