 Dear All respectable CCL members,
 	I know that it may be trivial but I was surprised with the following
 behavior. While doing a TS search the final output with normal termination show
 in the optimized Parameters section the following
 ! A11   A(4,5,7)  126.9034  -DE/DX = 0.0 !
  ! A12   A(2,8,9)  110.5261  -DE/DX = 0.0!
  ! A13   L(8,9,10,6,-1)  199.1901  -DE/DX = 0.0!
  ! A14   L(8,9,10,6,-2)  223.1914  -DE/DX = 0.0!
 ! D1    D(5,1,2,3)  5.1951   -DE/DX = 0.0!
 The A11 and D1 are normal angles and dihedral angels but for angle
 A13 and A14  what is the meaning of the numbers 8,9,10,6,-1 we usually need 3
 atom numbers to define an angle and 4 for dihedral so what is the need for 5
 numbers and I wonder what are there meaning?
 Thanks
