The rotational spectra of NiF in the electronic ground 2 state and the lowest electronically excited 2 state have been observed. The source of nickel atom was sputtering from a nickel electrode or nickel powder placed on a stainless steel electrode. The molecular constants have been determined by a

โฆ Synopsis
The modified CNDO/Z method (CNDO/s) has been applied to study the electronic structure utd geometry of ortho-and meta-difluorobcnzcnes in their ground and first excited sinplct states. Calculated density matrices have been transformed into o-and n-bond orders by the technique suggested earlier. Bond lengths have been calculated
