By combining our rearranged equation … (1)  with that for m*  we can obtain an expression for any phase, let’s say R,  free of the absorption coefficient:
	xR =   [ IhR  / KhR ]  /  [  ? (IiJ  / KiJ) ]
	 xR =  1 / ? ( ?RJ / SRJ)		… (4)
where: SRJ  is the ratio of intensities of peaks belonging to phases J and R respectively  ie SRJ  = IiJ / IhR
