Abstract
The \tildeA^1 A_2 \leftarrow \tildeX^1 A_1\left(4_0^2\right) magnetic dipole transitions of formaldehyde and formaldehyde-d2 have been investigated via 1+3 photon REMPI spectroscopy. Rotationally resolved spectra (resolution: 0.04cm-1) have been obtained and completely assigned. The rotational structure of the 42 level of the A1A2 state has been fitted with asymmetric top constants A,B, and C, the band center v0, and centrifugal constants DK, DJK, andDJ.
