Simplified Infrared Functional Group Correlation Chart One of the difficult aspects of infrared spectra interpretation is using spectral correlation charts as found in many textbooks. Althougi~these references are invalushle to the trained chemist in the interpretation of many spectra, they are too detailed and often too complex for beginning students. The most frequently encountered functional groups are difficult to locate on the charts or they are obscured by the presence of infrared absorption hands for functional groups which the beginning student will not encounter. To this end we have produced a. simplified version of an infrared functional group correletion chart. The chart has two advantages. First it presents only the most common functional groups encountered by the beginning student. Second, the char6 is drawn on a piece of chart paper for the Perkin-Elmer 700 Speetrophotometer, the instrument on which student spectra are measured.
Standard (a'/* X 11 in.) eopics me made available to ihe student and a wall-sized chart is located near the instrument. Additionally, transparent overhys are available for students to place over their spectra. t o assist them in correlatine structure with soectra. These transoarencies are also useful in classroom drill sessions bv. simolv . . superimposing tbe overlay correla'tion chart aver the transparency of the spectrum being studied. We have prepared a similar correlation chart for the Varian EM-300 nmr, which we now understand is commercially available from the instrument's manufacturer, Varirtn Anrtspeet. ALFREDL. MOYB T. A.
