Initialization of Force Constant Matrices

`$forceinit on`

is set, the force constant matrix
will be initialized as a unit matrix. Specifying the force constant initialization key
`diag=`*real*- Initialization with
*real*as diagonal elements. `diag=default`- Initial force constant
diagonals will be assigned the following default values:
internal coordinates : stretches 0.50 angles 0.20 scaling factors : s,p 1.50 d 3.00 exponents : uncontracted 0.15 contracted 10.00 contraction coefficients : 100.00 global scaling factor : 15.00 cartesian force constants : 0.50 `diag=individual`- Initial force constant
diagonals will be taken from

`$intdef fdiag=...`

or

`$global fdiag=...`

Similar initialization modes are NOT supported for geometry optimization in cartesian space and for the optimization of basis set parameters! `carthess`- Data group
`$hessian`(projected) is used.
