AbstractThe crystallographical expectation of different behaviour of crystals with asymmetric molecules against the optical antipodes of quartz was not exactly proved up to date. The weak asymmetry of the potential field of the crystal surfaces was probably the cause. We awaited a distinct effect from a substance consisting of large complex molecules like vitamin BThe epitaxial effect is extremely selective. The orientation of the vitamin crystals was splendidly positive upon the polished L-quartz surfaces activated by etching with HF, never upon R quartz. There were found and described 18 laws of orientation of the vitamin crystals upon the faces (101̄0), (1̄1̄20), (112̄0), (101̄1), (011̄1), (0001). The laws could be formulated as one-dimensional structure analogies.The structural interpretation of the molecular kinetics, i.e. adsorption, formation of H bridges between both active groups and seed formation gave a new outlook upon the existence of small molecular matrices of very different size at the surfaces for this catalytic process which leads to the macroscopic appearance of the overranging one-dimensional analogies. The proof of a total mismatch of every matrix system with respect to the vitamin upon the R quartz is especially interesting.
