_chemical.optical_rotation

Name:
_chemical.optical_rotation

Alias:
_chemical_optical_rotation

Definition:

   
     The optical rotation in solution of the compound is
     specified in the following format:
 
    '[\a]^TEMP^~WAVE~ = SORT (c = CONC, SOLV)'
 
     where: TEMP is the temperature of the measurement in degrees Celsius,
        WAVE is an indication of the wavelength of the light
             used for the measurement,
        CONC is the concentration of the solution given as the
             mass of the substance in g in 100 ml of solution,
        SORT is the signed value (preceded by a + or a - sign)
             of 100.\a/(l.c), where \a is the signed optical
             rotation in degrees measured in a cell of length l in
             dm and c is the value of CONC in g, and
        SOLV is the chemical formula of the solvent.

Example:

'[\a]^25^~D~ = +108 (c = 3.42, CHCl~3~)'
