Also included are some instructional documents on organic spectroscopy. A number of items are useful for instructors such as the IR comparitor. For a project summary, see: Merlic, C. A.; Fam, B. C.; Miller, M. M. "WebSpectra: Online NMR and IR Spectra for Students" J. Chem. Ed. 2001, 78, 118-120. http://www.merlot.org/merlot/viewMaterial.htm?id=82859 Get endless practice calculating molarity in a solution with this Bottomless Worksheet. At the click of a button, it creates ten more problems for you to solve (including finding moles/liter, moles, and liters of solution as separate problems). A printed copy and answer sheet is also available. http://www.merlot.org/merlot/viewMaterial.htm?id=87552 Draw a compound, and press the button below to find which functional groups it contains. http://www.merlot.org/merlot/viewMaterial.htm?id=82858 This Bottomless Worksheet is a way to practice calculating molar masses for organic and inorganic molecules. At the click of a button, it creates ten more problems for you to solve (complete with molecular name and formula). A printed copy and answer sheet is also available. http://www.merlot.org/merlot/viewMaterial.htm?id=82860 Get endless practice on using molar masses to convert between moles and grams with this Bottomless Worksheet. Ten more problems are always just a click away -- you can get a printed copy and answer sheet, too. Both organic and inorganic molecules are presented, including molecular names and formulae. http://www.merlot.org/merlot/viewMaterial.htm?id=76509 How quickly you can match common chemicals with their symbols? http://www.merlot.org/merlot/viewMaterial.htm?id=229151 The Chemistry Tutorials & Drills web site is designed for students of chemistry trying to get to grips with the subject. Topics currently covered are: The recognition of simple organic functional groups, VSEPR and balancing chemical reaction equations. http://www.merlot.org/merlot/viewMaterial.htm?id=447277 Exercises in predicting how many signals will appear in the proton NMR spectrum of a compound, and in matching compounds to spectra are given with detailed and pictorial feedback. Mirror planes of symmetry, local symmetry, chemical shifts, and simple splitting patterns are explained in detail. Resolution among signals and/or the lack thereof is explained for two of the spectra. http://www.merlot.org/merlot/viewMaterial.htm?id=439916 The structures of 12 molecules (drawn in ChemSketch) are given. The corresponding FT-IR spectra are given, in scrambled order, in a SoftChalk slideshow. With interactive SoftChalk labeling activities, the user matches functional groups/chromophores to spectral peaks/bands. Finally, with SoftChalk labeling exercises the user identifies each spectrum. Detailed feedback is given for each answer. IR charts are provided. Links to simulations which demonstrate the relationships of functional groups/chromophores/bonds to the frequencies of IR radiation they absorb, the types of vibrations produced by each absorption, and the spectral peaks/bands that result from each absorption are given. http://www.merlot.org/merlot/viewMaterial.htm?id=229237 Large collection of college-level introductory organic chemistry learning materials, including practice problems and exams, tutorials, lecture recordings, etc.
