K. Hasegawa et al., IN-SITU OBSERVATION OF THE CONCENTRATION GRADIENT LAYER AROUND A GROWING CRYSTAL OF LEUCINE COMPLEX, Journal of crystal growth, 166(1-4), 1996, pp. 925-929
The concentration gradient layer around a growing crystal of L-leucine
complex was observed using a Michelson interferometer. From the inter
ferograms and growth-rate measurements in the stagnant solution, we co
uld estimate the growth mode and the diffusion coefficient of the comp
lex of L-leucine (L-leu) and 3,4-dimethylbenzenesulfonic acid (o-DMBS)
. Growth rate versus surface supersaturation could be shown as R(<sigm
a)) = 2.35 x 10(-7) sigma(1.65), and the diffusion coefficient was est
imated to be 7.2 x 10(-10) m(2)/s. The estimated Stokes radius coincid
ed with the size of each molecule of L-leu and o-DMBS.
