This innovative tool is key to understanding Raman spectroscopy, a non-destructive chemical analysis technique that provides detailed information about chemical structure, phase and polymorphy, crystallinity, and molecular interactions.


The Raman Shift Calculator is a digital tool to compute the Raman shift, Δν, which measures the energy difference between the incident light and the scattered light in a sample. The calculator calculates the Raman shift by calculating the incident light's wavelength (λ₀) and the scattered light's wavelength (λ₁).

Detailed Explanations of the Calculator's Working

The Calculator works using the basic principle of Raman Scattering. It begins by taking the wavelengths of the incident and scattered light as input. Subsequently, it applies the Raman shift formula: Δν = (1 / λ₀) - (1 / λ₁), where the wavelengths are in consistent units. The calculated result provides invaluable insights into the molecular structure of the sample.

Raman Shift Formula and Variable Descriptions

The Raman shift formula, Δν = (1 / λ₀) - (1 / λ₁), is the core principle behind it. In this formula, Δν represents the Raman shift, λ₀ is the wavelength of the incident light, and λ₁ is the wavelength of the scattered light. It's crucial that both wavelengths are expressed in the same units for accurate and consistent results.


For instance, consider a situation where the incident light has a wavelength of 532 nm, and the scattered light is to have a wavelength of 560 nm. Using the Calculator, we find the Raman shift is approximately 3243 cm⁻¹, giving us essential information about the sample's chemical structure.
