Use the Analyze spectrum tool for analyzing the calculated spectra, graphical editing it and adding experimental ones. To show the Analyze Spectrum window click the menu Tools --> Analyze Spectrum.
26 Νοε 2024 · Spectroscopy Wavelength Calculator (UV-Vis, IR) is a specialized tool designed to assist scientists, chemists, and researchers in determining the specific wavelengths of light absorbed by a sample in the ultraviolet-visible and infrared regions of the electromagnetic spectrum.
Band gap of any material can be easily calculated by using UV-Vis absorption wavelength or lamda max value of the sample.
This calculator can be used to determine the concentration of any sample by using absorbance and molar absorptivity values.
28 Αυγ 2022 · The UV-vis region of energy for the electromagnetic spectrum covers 1.5 - 6.2 eV which relates to a wavelength range of 800 - 200 nm. The Beer-Lambert Law, Equation \ref{1} , is the principle behind absorbance spectroscopy.
Calibration of the UV spectrophotometer including control of absorbance using potassium dichromate solution, resolution power using toluene in hexane, limit of stray light and wavelength accuracy.
Ultraviolet visible (UV-Vis) spectrophotometers use a light source to illuminate a sample with light across the UV to the visible wavelength range (typically 190 to 900 nm).
