More information on the manner in which spectra in this collection were collected can be found here. Notice: Concentration information is not available for this spectrum and, therefore, molar absorptivity values cannot be derived.

Purpose: Use the infrared vibrational spectrum of HCl and DCl to obtain the following: Internuclear Separation, r Force Constant, k Evidence of the Isotope

Infrared spectroscopy is an important analytical tool to determine the structure of molecules. Fourier transform infrared spectroscopy was used to study the vibrational and rotational motions of diatomic molecules hydrogen chloride, HCl and deuterated chloride, DCl.

The FT-IR spectrum of HCl gas is a classic demonstration of quantum behavior. The diatomic, HCl, has only one IR-active vibrational mode. Yet, a close look at its IR spectrum shows interesting structure that can only be explained by quantization and coupling of the molecule's rotations to the vibrational motions.

Here we discuss the vibration and rotations of a diatomic molecules such as HCl, based on the experimental results on the infrared absorption spectra. Infrared spectroscopy (IR spectroscopy) is the spectroscopy that deals with the infrared region of the electromagnetic spectrum, that is light with a longer wavelength and lower frequency than ...

Record HCl/DCl spectrum using "Obtaining an FTIR Spectrum using the Nicolet iS50" below. Once all data has been collected, return the gas cell to the working manifold and safely evacuate all remaining HCl/DCl.

The purpose of this experiment is to analyze the rotational-vibrational spectrum of Hydro-gen Chloride gas in order to calculate the equilibrium bond distance, the force constant, the anharmonic constant, the vibration-rotation interaction …

With the high-resolution option for the ALPHA II FT-IR spectrometer, one can obtain excellent HCl vapor spectra measured in a gas cell. Analysis of the HCl spectrum, making full use of the OPUS peak pick software installed on the ALPHA II Touch-PC or Windows PC, gives molecular constants that are fully consistent with the values published in ...

A classic among molecular spectra, the infrared absorption spectrum of HCl can be analyzed to gain information about both rotation and vibration of the molecule. The absorption lines shown …
