21. In contrast to 2DNMR, nonlinear two-dimensional infrared spectroscopy also involves the excitation to overtones. 22. The debate was finally resolved by infrared spectroscopy , which revealed cadmium hydroxide and nickel hydroxide. 23. Subsequent breath analyzers have converted primarily to infrared spectroscopy . 24. A few examples of absorption are ultraviolet visible spectroscopy, infrared spectroscopy , and X-ray absorption spectroscopy. 25. Caesium nitrate prisms are used in infrared spectroscopy , in x-ray phosphors, and in scintillation counters. 26. Infrared spectroscopy shows bands at 650, 1210, 1440, 1650 and 1760 cm " 1.27. Methods used to measure neural responses to speech include event-related potentials, magnetoencephalography, and near infrared spectroscopy . 28. Graphene also accommodates surface plasmons, observed via near field infrared optical microscopy techniques and infrared spectroscopy . 29. NESSI is expected to devote about 50 nights per year for surveying exoplanets via infrared spectroscopy . 30. As well as X-ray diffraction, NMR and infrared spectroscopy are common techniques used to determine structure.
