Compound Information: Molecular formula C16H25NO2. - [Voiceover] Different molecules can absorb different wavelengths of light and if a molecule happens to absorb light in the ultraviolet or the visible region of the electromagnetic spectrum we can find the wavelength or wavelengths of light that are absorbed by that compound by using a UV/Vis spectrophotometer. Spectroscopy. UV-visible spectroscopy is especially informative for molecules that contain conjugated π bonds. These movements are called bending vibrations. Compound Information: Molecular formula C15H22O2. 2014 Final Exam Part II.2. Notes: This problem focuses on conformational and stereochemical analysis in a fused 5,6 ring system. Electromagnetic radiation with a frequency of about 60 megahertz (MHz) can supply the energy needed to convert the lower energy state to the higher one. About this unit.

The study of organic … Notes: A simple but challenging molecule with a rich 1H NMR spectrum. Techniques: Negative ion FAB and ESI mass spectrometry. Stretching and bending vibrations in organic compounds such as 5-hexene-2-one represent different energy levels within a molecule that can be detected by using infared spectroscopy. Download Individual Chapters, the Entire Semester, Even the Full Course of Organic Chemistry Notes. When placed in a strong external magnetic field, such nuclei can assume different energy states; in the simplest case, two energy states are possible. Notes: This problem was the most popular of the 2013 final exam Part II problems. (2014-MT-II.2.pdf) It was the most popular problem of the 2014 final exam Part II problems. Many (but not all) atomic nuclei have a small magnetic field, which makes them behave somewhat like tiny bar magnets. Notes: Electron ionization (EI) mass spectra are shown for five transition metal acetylacetonate (acac) complexes. Notes: A small molecule with interesting IR and NMR spectra. (2012-MT-I.3.pdf) This archive includes six types of problems from the midterm and final exams of my Chem 203 Organic Spectroscopy class. Techniques: EI-MS; IR (thin film on NaCl plates); 500 MHz 1H NMR in CDCl3; 125.8 MHz 13C NMR, DEPT 90, and DEPT 135 in CDCl3. 2011 (fall) Final Exam Part II.2. The Gamma radiation is the energy source in this type of spectroscopy, which includes activation analysis and Mossbauer spectroscopy. 2011 (fall) Midterm Exam Part I.2a. Techniques: 500 MHz 1H NMR, 125.8 MHz 13C NMR, DEPT, COSY, TOCSY (20 ms mixing time), HMQC, HMBC, NOESY, and HSQC-TOCSY spectra with 5-, 10-, 25-, and 50-ms mixing times. Related to codeine.
