Methanol, by way of example, absorbs at wavelengths under 205 nm, and water below a hundred ninety nm. For those who had been utilizing a methanol-drinking water mixture as being the solvent, you'd probably thus really need to make use of a wavelength better than 205 nm to avoid Bogus readings in the solvent.The particular intermolecular interactio
