A systematic search for the unknown molecule selenoformaldehyde, H2C=Se, starts with the precalculation of its ionization pattern from ab-initio-PNO-CI and CEPA wave functions.The selenium precursors H3CSeSeCH3, H3CSeCN, H3CSeCl, and (H2CSe)3 are pyrolyzed in a flow system under PE spectroscopic real-time analysis: Applying "computerized spectra stripping" to the PE spectra of the pyrolysis mixtures, an ionization pattern can be extracted which correlates satisfactorily with the quantum chemical prediction for H2C=Se.To further support the assignment, selenoacetaldehyde, CH3CH=Se, and selenocarbonyl difluoride, F2C=Se, are prepared by thermal monomerization of 3 and (F2CSe)2, respectively.
