    What could be the compound in this spectra with peaks at 154 and 154+2?

    No there shouldn't be a significant 118+2 peak, because Cl is being lost and so the 37Cl isotope won't be present anymore. Hence there is no 3:1 peak ratio in the mass spectra at 118 & 120

    What could be the compound in this spectra with peaks at 154 and 154+2?

    Sure. Strong IR band at ~1700 indicates presence of carbonyl oxygen. In a Spectroscopy book I've got from the library, the band at ~1200 is supposedly indicative of a saturated ester. The band at ~2900 also suggests an ester In the mass spec. The molecular ion peak is 154, with an M+2...

    Hi guys As part of my degree I've got to analyses a set of spectras unknown compounds. I've managed to do them all so far, but seem to be struggling on this one particular set. Here's the spectra that I have to analyse: http://imgur.com/a/oVNYe So far I think it might be an ester with a Alkyl...
