Experimental determination of MCD

In the case of discrete bands, comparison between the experimental data and theoretically calculated values can be made by use of the method of the moments (Stephens, 1968). 

The wave number Vg is some chosen value about which the moments are taken. In MCD it is usually the wave number value for which the first-order moment in absorption becomes zero  

The CLi contribution integrates to zero because of Eq. (58) where v can simply be replaced by v. In this way it is possible to extract (58q + Co/fcT) in the presence of large CLi terms. 58o and Cq can be further separated by measuring data at different temperatures. 

With the use of Eq. (185) the first-order moment for MCD becomes (wifh H in fesla)
