What is the range of IR spectroscopy in cm-1?

The mid-infrared, approximately 4000-400 cm-1 (2.5-25 μm) may be used to study the fundamental vibrations and associated rotational-vibrational structure. The far-infrared, approximately 400-10 cm-1 (25-1000 μm), lying adjacent to the microwave region, has low energy and may be used for rotational spectroscopy.

What is the range of IR spectrophotometer?

The wavelengths of infrared radiation are between 0.8 and 250 μm. The units that are typically used for infrared spectroscopy are wavenumbers (which is cm-1). IR spectroscopy analyzes radiation between 40 to 13,000 cm-1.

How can you tell 1-propanol?

3.2.1Physical Description N-propanol appears as a clear colorless liquid with a sharp musty odor like rubbing alcohol. Flash point 53-77°F. Autoignites at 700°F. Vapors are heavier than air and mildly irritate the eyes, nose, and throat.

How are the spectra of ethanol and n-propanol measured?

In the present work, the spectra of ethanol and n··propanol have been measured from 2 to 40 f.1. in the vapor state and from 2 to 15 f.1. in solutions of. 0014 and OS2. Because of the similarity in struc·· ture of these alcohols, the positions of many absorp·· tion bands appear in the same regions.

Which is the correct molecular weight of propanol?

Propanol PubChem CID 1031 Synonyms 1-propanol propanol Propan-1-ol Propyl a Molecular Weight 60.10 Date s Modify 2021-05-22 Create 2005-03-26

What do you need to know about the IR spectrum?

The IR Spectrum Table is a chart for use during infrared spectroscopy. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups.

What is the flash point of n-propanol?

N-propanol appears as a clear colorless liquid with a sharp musty odor like rubbing alcohol. Flash point 53-77°F. Autoignites at 700°F. Vapors are heavier than air and mildly irritate the eyes, nose, and throat. Density approximately 6.5 lb / gal.
