Perhalogenated pyridine derivatives give negative molecular ions which undergo various fragmentation processes upon negative ion chemical ionisation. The similarities between highly fluorinated negative molecular and fragment ions that are preferentially formed in the gas and solution phases are out

## Abstract Electron capture by and the subsequent fragmentation of a series of eleven fluorinated ฮฒโ€diketones of general formula CF~3~COCH~2~COR has been studied in an MSโ€50 mass spectrometer. Consecutive loss of two HF molecules from molecular anions occurs with all compounds, as does elimination

## Abstract The fragmentation behaviour of a series of six avermectins and two of their derivatives has been studied in the negativeโ€ion mode in the presence of ammonia. In contrast with positiveโ€ion mass spectra the negativeโ€ion spectra show abundant ions in the high mass region. Molecular mass de
