    • To remedy this problem, a multiconfiguration self-consistent-field (MCSCF) approach may be used to appropriately describe these singlet diradical systems. However, using the current computing facility, it is not practical to implement this multi-reference method (e.g., CASSCF) since it may not allow us to include the entire reactive space for all channels.

    • note
    • The deposited energy (2hv=186 kcal/mol) gives this available energy since the molecule was cooled in the molecular beam expansion; no appreciable thermal energy. There is no one photon absorption for these cyclic ethers at the wavelength (307 nm) of the experiment.
