Ether on ir spectra
WebIR bandwidth ranges from 4000 cm -1 to 400 cm -1 . IR spectroscopy depending on Hooke's Law, make the assumption that when a bond connects two atoms or particles, thus the vibration frequency may be described as follows: ν = 1 / 2 π κ μ. Where, 𝜅 is bond force constant, ν is the frequency, 𝜇 is reduce mass where m1 and m2 are the ...
