In AMBER each atom has a designated type which is defined to set of parameters 
in AMBER.  It appears that nitro groups are not able to be characterized by 
the existing atom type definitions.  Are NO2 groups able to be studied with 
AMBER?  Have the parameters for NO2 been determined previously?  Is it 
possible to define your own parameters manually and if so how?  Is there a 
systematic method to how parameters are defined in AMBER?  Any assistance 
would be greatly appreciated.
