-! This subroutine calculates the derivatives of the consecutive virtual
-! bond vectors and the SC vectors in the virtual-bond angles theta and
-! virtual-torsional angles phi, as well as the derivatives of SC vectors
-! in the angles alpha and omega, describing the location of a side chain
-! in its local coordinate system.
-!
-! The derivatives are stored in the following arrays:
-!
-! DDCDV - the derivatives of virtual-bond vectors DC in theta and phi.
-! The structure is as follows:
-!
-! dDC(x,2)/dT(3),...,dDC(z,2)/dT(3),0, 0, 0
