| infrared radiation | Electromagnetic radiation with wavelengths between 750 nanometres and 1,000,000 nanometres (or 1 millimetre). This is more commonly known as heat energy. (09 Oct 1997) |

| infrared ray | See: infrared. (05 Mar 2000) |
| infrared rays | That portion of the electromagnetic spectrum usually sensed as heat. Infrared wavelengths are longer than those of visible light, extending into the microwave frequencies. They are used therapeutically as heat, and also to warm food in restaurants. (12 Dec 1998) |
| infrared spectroscopy | The study of the specific absorption in the infrared region of the electromagnetic spectrum; used in the study of the chemical bonds within molecules. (05 Mar 2000) |
| infrared spectrum | The part of the invisible spectrum of wave length just longer than that of visible red light. Synonym: thermal spectrum. (05 Mar 2000) |
