Infrared (IR) spectrometry is a versatile analytical technique used to identify and characterize chemical compounds based on their interaction with infrared light. The basic instrumentation for IR spectrometry consists of several key components that enable the measurement and analysis of infrared spectra.

1. IR Light Source: The light source in an IR spectrometer emits a broad spectrum of infrared radiation. Commonly used sources include nichrome wire or a globar, which produce a continuous spectrum across the mid-infrared region.

2. Sample Compartment: The sample compartment holds the sample to be analyzed. It typically consists of a sample holder or cell, which can accommodate solid, liquid, or gas samples. The sample is placed in the path of the infrared beam.

3. Interferometer: The interferometer is a crucial component in IR spectrometers. It splits the incoming infrared beam into two paths and then recombines them to create an interference pattern. This ___ ____ ___ ________ ________ ______ __________ _________ _________ __________ ______ _______.
