1600 - 1850 cm-1 wavenumber corresponds to the C=O double bond region on an IR spectrum.
Which of the following are wavenumber units in IR spectroscopy?
- Wavenumbers are the most commonly used units in infrared spectroscopy.
- IR spectroscopy examines radiation with wavelengths ranging from 40 to 13,000 cm^-1.
- The stretching frequencies of most alkyne CC bonds range between 2100 and 2200 cm^-1. Terminal alkynes typically produce moderately intense CC stretching signals.
- IR spectroscopy can be used to determine which functional groups are present in a compound. The IR spectrum is created by recording the frequencies at which a polar bond's vibration frequency is equal to the infrared light's frequency.
- Infrared spectroscopy (IR spectroscopy) is the study of the electromagnetic spectrum's infrared region, which contains light with a longer wavelength and lower frequency than visible light. It covers a variety of techniques, the majority of which are based on absorption spectroscopy.
