Refractive index (real part) of wet mesophyl cell wall (400-2500nm)
computed using the Dale and Glasdone law (Baranoski 2006) and
considering the refractive index of water provided by Palmer and Williams (1974)
as well as the refractive index of dry mesophyl cell wall, which
was estimated to be 1.5479. This value was also obtained using
the Dale and Gladstone law and considering the refractive index of
wet mesophyll cell wall measured by Woolley (1975) at 800nm equal
to 1.415 (Woolley 1975). Data resolution equal to 5nm:
