“…The determination of methoxvchlor [2,2-bis(p-methoxyphenyl)-!, 1,1-trichloroethane] on paperboard is developed by Jennings and Edwards (109). They extract the methoxychlor with cyclohexane and employ the absorption maximum at 230 µ with a correction for irrelevant absorption.…”

THISreview covers the 2-year period since the last one in this series (177) was written. The publication of ultraviolet absorption spectra has continued at a rapid rate. Most of these spectra are obtained for the purpose of studying correlations between structure and spectra, and they are not included in this review. GENERAL TOPICSA theoretical derivation of Beer's law is given by Strong (194,196) who extends the treatment to include the effect of the finite pass-band of the spectrophotometer. The derivation and validity of Lambert's and Beer's laws are discussed by Luck (131) with special attention to a spectrum which consists of overlapping lines. Some examples of apparent deviations from Beer's law• reported by Ungnade, Kerr, and Youse (309) are attributed by Yandenbelt, Henrich, and Bash (311) to low solvent transmittance since they were not observed with 0.02-cm. absorption cells.Rose (176) discusses deviations from Beer's law produced by scattering from suspended particles. A particularly helpful paper by Goldring et al. ( 81) treats the causes of departures from theory in spectrophotometry, principally the instrumental factors.Gridgeman (85) presents the theoretical background for the evaluation of the reliability of photoelectric photometry and includes a critique of the transmittance-ratio method developed by Ringbom.
