| 31. | Infrared spectroscopy has been used to obtain information about the different conformations of the methanium ion.
|
| 32. | Infrared Spectroscopy is also used in gas leak detection devices such as the DP-IR and EyeCGAs.
|
| 33. | He had utilized several experimental techniques, including X-ray and neutron diffraction, infrared spectroscopy, and M�ssbauer spectroscopy.
|
| 34. | The technique is called Fourier transform infrared spectroscopy.
|
| 35. | Infrared spectroscopy yields similar, but complementary, information.
|
| 36. | NMR and infrared spectroscopy ) are better at determining the structural features and identity of unknown compounds
|
| 37. | Gas-phase infrared spectroscopy by Yeh and others ( 1989 ) has shown that both forms are stable.
|
| 38. | Brugger, et al . ( 1997 ) used infrared spectroscopy to measure water content in Rom�ite crystals.
|
| 39. | Infrared spectroscopy suggests the electronic structure is a zwitterion rather than a biradical as some had proposed.
|
| 40. | In 1975 its structure was descripted in base of mass spectrometry, infrared spectroscopy and nuclear magnetic resonance.
