Constant deviation spectroscopy is a technique used to measure the wavelengths of light. It works by diffracting light with a fixed diffraction grating at a constant angle, regardless of the wavelength. By measuring the position of the diffracted light, the wavelength can be determined. This method is often used in optical spectrometers to provide accurate and reliable spectroscopic results.
The force constant is a measure of the strength of a chemical bond. In IR spectroscopy, it affects the vibrational frequency of a molecule, which determines the position of peaks in the IR spectrum. Higher force constants result in higher vibrational frequencies and shifts IR peaks to higher wavenumbers.
Mercury lamps are chosen for constant deviation spectrophotometry because they emit strong lines at characteristic wavelengths, making them suitable for calibration purposes. The narrow spectral lines produced by mercury lamps help in accurately determining the deviation and dispersion properties of the spectrometer. Sodium lamps, on the other hand, have broader emission lines which can affect the precision of the measurements in constant deviation spectrophotometry.
An ordinary prism disperses light based on varying angles of refraction, resulting in different colors being separated at different angles. A constant deviation prism disperses light in such a way that all colors are dispersed at a constant angle, maintaining a consistent level of separation irrespective of wavelength.
No, Raman spectroscopy is not emission spectroscopy. Raman spectroscopy involves the scattering of light, while emission spectroscopy measures the light emitted by a sample after being excited by a light source.
Yes, there are different types of Raman spectroscopy, including spontaneous Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and resonance Raman spectroscopy. Each type utilizes different methods to enhance the Raman scattering signal and provide insights into different sample properties.

It means that equilibrium may be attained at widely separated values.
It is named after the type of prism used in the instrument. A constant deviation prism has the property that the angle between light entering the prism (the incident light) and light exiting the prism (the emergent light) is always the same, no matter what the angle of the incident light to the prism.
Emission photo-spectroscopy and Absorption photo-spectroscopy.
Yes, there are different types of Raman spectroscopy, including spontaneous Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and resonance Raman spectroscopy. Each type utilizes different methods to enhance the Raman scattering signal and provide insights into different sample properties.
What is mean deviation and why is quartile deviation better than mean deviation?
Fluorescence spectroscopy is a type of spectroscopy that analyzes fluorescence from a provided sample. This uses a beam of light, often an ultraviolet light which then causes absorption spectroscopy to occur.
