Slow evaporation of an aqueous solution containing equimolar quantities of </span><i><span style=\"font-family:Verdana;font-size:12px;\">L</span></i><span style=\"font-family:Verdana;font-size:12px;\">-proline
and succinic acid (for 1) and </span><i><span style=\"font-family:Verdana;font-size:12px;\">L</span></i><span style=\"font-family:Verdana;font-size:12px;\">-threonine and zinc acetate (for 2)
results in the fractional crystallization of succinic acid (in the first case)
and </span><i><span style=\"font-family:Verdana;font-size:12px;\">L</span></i><span style=\"font-family:Verdana;font-size:12px;\">-threonine (in the second case) and not any novel organic
non-linear optical (NLO) crystals. In this paper, the usefulness of infrared
spectra for correct product characterization is demonstrated.</span></span>
