Dear MathGroupers, I'm studying a branch of molecular dynamics, so I need to be familiar with rotating reference systems, and so son. Spherical harmonics are standard in Math, I know,and I've found the additional package about 3D rotation, but I also need to work with so-called Wigner matrices Dpq(a), that are a sort of spherical tensors of rank a=1,2,... I'm novice with the argument, but they have almost nothing to do with Wigner's 3J Symbol ,page 730 of Math3 manual, I suspect. Has anybody a reference for a suitable implementation of them, with all the necessary combinatorial rules? Or at least some easy (as possible) reference texts? Any suggestion will be appreciated. Thanks in advance. Roberto Pratolongo c/o IMAG-CNR, Genoa, Italy Email: rp at imag.ge.cnr.it
