Spectrophotometry is an important branch of spectroscopy that focuses on the technique of measurement. In this technique, the amount of light that a sample absorbs at a particular wavelength is measured and used to determine the concentration of the sample by comparison with appropriate standards or reference data. The most useful measure of light absorption is the absorbance (A), also commonly called the optical density (OD). The absorbance is defined as A = log I0 / I where I0 is the intensity of light that is incident on the sample and Iis the intensity of light that is transmitted by the sample. The absorbance of a sample can be related to the concentration of the absorbing species through Beer's law: A = ε cl where c is concentration, usually measured in moles per liter; l is the length of the light path, usually 1 cm; and ε is a proportionality constant known as the molar extinction coefficient, with the units of liters per mole per centimeter. The value of ε is a function of both the particular compound being measured and the wavelength.

Is Raman spectroscopy is emmission spectroscopy?
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.
Are there different types of raman spectroscopy?

What is the basic principle of raman spectroscopy?
Raman spectroscopy is based on the inelastic scattering of light, where photons interacting with a sample undergo energy exchange, resulting in shifts in wavelength that can be used to identify molecular vibrations. By analyzing these shifts, information about molecular composition and structure can be obtained.
What is laser raman spectroscopy?
Raman spectroscopy is the vibrational spectroscopy. The ancient days the scientist use sunlight as a source for getting spectrum.but the modern world, the scientist use high energy laser for characterisation.so, it is called laser raman spectroscopy.

Who began the study of spectroscopy?
Spectroscopy can be traced back to Sir Isaac Newton's experiments with the prism in the 17th century, which led to the discovery of the visible spectrum of light. However, the modern study of spectroscopy was advanced by physicists such as Gustav Kirchhoff and Robert Bunsen in the 19th century, who developed the principles of spectroscopy that laid the foundation for its use in modern science.

What are the differences between IR spectroscopy and UV-Vis spectroscopy in terms of their applications and principles?
IR spectroscopy and UV-Vis spectroscopy are both analytical techniques used to study the interaction of light with matter. IR spectroscopy is primarily used to identify functional groups in organic molecules by measuring the vibrations of chemical bonds. It is sensitive to the presence of specific functional groups such as carbonyl, hydroxyl, and amino groups. UV-Vis spectroscopy, on the other hand, is used to determine the electronic transitions of molecules, providing information about the presence of conjugated systems and chromophores. It is commonly used to quantify the concentration of a compound in solution. In terms of principles, IR spectroscopy measures the absorption of infrared radiation by molecules, while UV-Vis spectroscopy measures the absorption of ultraviolet and visible light. The differences in the types of radiation used result in different applications and information obtained from each technique.
