Integrated absorption coefficient

NettetThe fundamental parameter controlling absorption over length L is the spectral absorption coefficient, k ν. Our next step is to establish a relationship between k ν and the fundamental molecular parameters that govern the “strengths” and “shapes” of absorption lines, namely the Einstein coefficients and line-broadening coefficients . NettetIt can simply obtained by multiplying the absorption coefficient by the molecular weight. Thus, ϵ = 0.0376 x 100 = 3.76 L·mol -1 ·cm -1 The Importance of Concentration The …
