Electron ionization mass spectra of 1,2-dihydro-2-[2'pyridyl, 4'-pyridyl, 2
',6'-pyrimidyl)-3H-indazol-3-ones (2a-c) and their related compounds (1a-c)
are described with the help of EIMS. The molecular formulae are further co
nfirmed by HREIMS peak matching of molecular ion peaks exhibited by EIMS.
