Routine Descriptions

 NAME:
        KNMHC

 PURPOSE:
        Returns an array of reaction rates for various non-methane 
        hydrocarbon reactions as a function of temperature and pressure.

        NOTE: Reaction rates may need updating to the latest JPL dataset.

 CATEGORY:
        Atmospheric Sciences

 CALLING SEQUENCE:
        RESULT = KNMHC( T, P [, Keywords ] )

 INPUTS:
        T -> Temperature in [K].

        P -> Pressure in [hPa].

 KEYWORD PARAMETERS:
        NAMES -> Returns to the calling program a list of the names
             for the various chemical species 

 OUTPUTS:
        RESULT -> An array of rate constants corresponding to
             the species contained in NAMES.
        

 SUBROUTINES:

        ================================
        KTROE (function)

 REQUIREMENTS:
        None

 NOTES:
        (1) This should probably be rewritten to return a structure.
        (2) Definitely needs updating of rate constants.

 EXAMPLE:
        RESULT = KNMHC( 300, 1000, NAMES=NAMES  )
        PRINT, NAMES
          CO CH4 C2H2 C2H4 C2H6 C3H6 C3H8 i-BUT CH3CL
        PRINT, RESULT

          3.76143e-14

             ; Compute rate constants for 300K and 1000hPa pressure

 NAME:
        KTROE

 PURPOSE:
        compute reaction rate coefficient for a 3rd order reaction
        using Troe's formula as given in JPL97-4

 CATEGORY:
        Atmospheric Sciences

 CALLING SEQUENCE:
        k=KTROE(T,p,k0300,n,kinf300,m [,keywords])

 INPUTS:
        T --> temperature in K

        p --> pressure in mbars

        k0300, n --> constants to get k0(T)  { see JPL97,table 2 }

        kinf300, m --> constants to get kinf(T)  { see JPL97,table 2 }

 KEYWORD PARAMETERS:
        k0, kinf, fc --> will return individual terms of the Troe expression

 OUTPUTS:
        K -> a rate coefficient

 SUBROUTINES:
        None

 REQUIREMENTS:
        None

 NOTES:
        no error checking is done except for the correct 
        number of arguments
