 Alert Level C:



THETM_01  Alert C The value of sine(theta_max)/wavelength is less than 0.590    
          Calculated sin(theta_max)/wavelength =    0.5768                      

PLAT_369  Alert C Long   C(sp2)-C(sp2) Bond  C(1)   -   C(2)   =       1.53 Ang.


 0 Alert Level A = Potentially serious problem

 0 Alert Level B = Potential problem
