_cell_volume

Name

'_cell_volume'

Category: cell

Data type: numb (with optional s.u. in parentheses)

Enumeration range: 0.0 -> infinity

Units: A^3^ ( cubic angstroms)

Definition

    	
   Cell volume V in angstroms cubed.

   V = a b c [1 - cos^2^(alpha) - cos^2^(beta) - cos^2^(gamma)
               + 2 cos(alpha) cos(beta) cos(gamma) ] ^1/2^

   a     = _cell_length_a
   b     = _cell_length_b
   c     = _cell_length_c
   alpha = _cell_angle_alpha
   beta  = _cell_angle_beta
   gamma = _cell_angle_gamma
