Hi,

As Dr. Smith pointed out, there is a missing angle parameter in
$AMBERHOME/dat/leap/parm/frcmod.ff03ua for HID C2-CC-CV. I made a patch for
this angle, here it is:

----------------------------------------------------------------------------
--- dat/leap/parm/frcmod.ff03ua.orig 2006-08-10 19:50:26.000000000 -0700
+++ dat/leap/parm/frcmod.ff03ua 2006-09-06 17:24:14.000000000 -0700
.. -66,6 +66,7 ..
 C2-CC-NA 70.0 120.00 AA his
 C2-CC-CW 70.0 120.00 AA his
 C2-CC-NB 70.0 120.00 AA his
+C2-CC-CV 70.0 120.00 AA his
 C3-C1-OH 50.0 109.50
 C1-OH-HO 55.0 108.50
 CT-C1-OH 50.0 109.50
