1. Introduction
IR spectroscopy is used for analysis of vibrational-rotational transitions in molecules. IR have an affect on vibrational, rotational, electronic transition of molecule , especially vibrational transition.
In this experiment, we use Fourier transform infrared spectroscopy to study the vibrational and rotational motions of diatomic molecules HCl ,DCl.

2. Experimental method
1. Assemble IR cell ; Grasp the edge of the lid, insert the CaF2 glass(window), and place them on both sides of the cell. * windows are hygroscopic, so keep them away from finger or moisture.
2. Turn on the FT-IR spectrometer and connected computer. Open the program OMNIC. Select Smart Accessory Change-“Smart OMNI – Transmission Accessory”.
3. Click <Exp Set > and set Resolution of 4.
4. Measure the background first using FT-IR spectrometer, Resolution 4. Place a blank gas cell in the holder of the spectrometer.
Click <col bkg> button to collect background data.
