| Abstract: | The molecular weights of a series of 1H-2, 3-Dihydro-1-Pyrrolizinone derivatives have been rapidly determined by LDI-TOF-MS.No matrix is needed to assist the desorption and ionization processes of the samples.The results indicate that the experimental values is identical with the theoretical values and LDI-TOF-MS is a rapid, simple and accurale method for the molecular weight determination of 1H-2, 3-Dihydro-1-Pyrrolizinone derivatives. |
