Takeshi Hasegawaendurchmesser berücksichtigt. Für jede Schwingungsform wurden drei Frequenzkurven (Bild 82 — 84) erstellt, die sich jeweils durch Variation eines der drei Parameter Scheibenst?rke, Rippenst?rke oder Bandagenst?rke ergeben mit dem konstanten Wert von 30 mm für die beiden übrigen Parameter. Die Ableit

Fundamentals of FT-IR,mostly been excluded, and instead FT-IR is commonly found in a laboratory. In this chapter, however, a dispersion-type spectrometer is described first to explain the principle of absorption spectroscopy, followed by the FT technique.

Infrared Spectroscopy as a Vibrational Spectroscopy,e molecular vibrations are decomposed into independent fundamental vibrations, which are called normal modes. In many cases, a normal mode is located on a chemical group in a nearly isolated manner. Thanks to this characteristic, IR spectroscopy is quite useful to discuss molecular structure with respect to each chemical group.

Infrared Spectroscopy as a Vibrational Spectroscopy,r characters are represented by the molecular conformation, hydrogen bonding, crystallinity, and orientation as well as the primary chemical structure. If a vibration-excited molecule yields a single band, the spectral information would be too short to reveal the molecular structure. Fortunately, th

Fundamentals of FT-IR,f a UV-vis spectrometer involving a dispersive optical element represented by a prism or a diffraction grating. Fortunately, however, in the IR region, great detectors are available responding a low-frequency modulated light, which enables us to employ a totally different measurement principle using
