between 780 nm and 1
Infrared radiation (IR), also known as thermal radiation, is that band in the electromagnetic radiation spectrum with wavelengths above red visible light between 780 nm and 1 mm. IR is categorized as IR-A (780 nm-1.4 µm), IR-B (1.4-3 µm) and IR-C, also known as far-IR (3 µm-1 mm).

What is the range of IR wavelength?

The infrared range is usually divided into three regions: near infrared (nearest the visible spectrum), with wavelengths 0.78 to about 2.5 micrometres (a micrometre, or micron, is 10-6 metre); middle infrared, with wavelengths 2.5 to about 50 micrometres; and far infrared, with wavelengths 50 to 1,000 micrometres.

What are the ranges of different types of spectrum?

Overview Over In Situ and Operando Spectroscopic Techniques

Region	Wavelength range	Wavenumber range
Mid-Infrared (MIR)	20–2.5 μm	500–4000 cm− 1
Near-Infrared (NIR)	2.5–0.75 μm	4000–13,333 cm− 1
Visible (VIS)	0.75–0.4 μm	13,333–25,000 cm− 1
Ultraviolet (UV)	0.4–0.122 μm	25,000–81,967 cm− 1

What is the range of mid IR radiation?

Beyond about 1.1 microns, infrared emission is primarily heat or thermal radiation….

SPECTRAL REGION	Mid-Infrared
WAVELENGTH RANGE (microns)	5 to (25-40)
TEMPERATURE RANGE (degrees Kelvin)	(92.5-140) to 740
WHAT WE SEE	Planets, comets and asteroids Dust warmed by starlight Protoplanetary disks

Can you see near infrared?

The human eye can detect the visible spectrum of the electromagnetic spectrum — a range of wavelengths between 390 to 700 nanometers. Louis discovered that contrary to prior beliefs, the human eye is in fact capable of seeing infrared light — but only under certain conditions.

Can infrared be harmful?

Medical studies indicate that prolonged IR exposure can lead to lens, cornea and retina damage, including cataracts, corneal ulcers and retinal burns, respectively. To help protect against long-term IR exposure, workers can wear products with IR filters or reflective coatings.

Is there a chart for the IR spectrum?

IR Spectrum Table & Chart 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. There are two tables grouped by frequency range and compound class.

What is the typical absorption range of IR?

IR ABSORPTION RANGE The typical IR absorption range for covalent bonds is 600 – 4000 cm-1. The graph shows the regions of the spectrum where the following types of bonds normally absorb. For example a sharp band around 2200-2400 cm-1would indicate the possible presence of a C-N or a C-C triple bond.

What is the frequency of the IR table?

Frequency (cm-1) intensity water OH Stretch 3700-3100 strong alcohol OH stretch 3600-3200 strong carboxylic acid OH stretch 3600-2500 strong N-H stretch 3500-3350 strong stretch ~3300 strong =C-H stretch 3100-3000 weak
