Steps to interpret a mass spectrum. 1. Look for the molecular ion peak. This peak (if it appears) will be the highest mass peak in the spectrum, except for isotope peaks. Nominal MW (meaning=rounded off) will be an even number for compounds containing only C, H, O, S, Si. Nominal MW will be an odd number if the compound also contains an odd ...
