| spectroscope | <instrument, physics> An optical instrument for forming and examining spectra (as that of solar light, or those produced by flames in which different substances are volatilized), so as to determine, from the position of the spectral lines, the composition of the substance. Origin: Spectrum + -scope. Source: Websters Dictionary (01 Mar 1998) |

| spectroscopic | Relating to or performed by means of a spectroscope. (05 Mar 2000) |
| spectroscopical | Of or pertaining to a spectroscope, or spectroscopy. Spectroscop"ically. Source: Websters Dictionary (01 Mar 1998) |
| spectroscopist | One who investigates by means of a spectroscope; one skilled in the use of the spectroscope. Source: Websters Dictionary (01 Mar 1998) |
| spectroscopy | <procedure> Spectroscopy is the science of measuring the emission and absorption of different wavelengths (spectra) of visible and non-visible light, this can be done via a spectroscope, which consists of a slit, prism, collimator lens, object lens, and a grating. (09 Oct 1997) |
| spectroscopy, fourier transform infrared | A spectroscopic technique in which a range of wavelengths is presented simultaneously with an interferometer and the spectrum is mathematically derived from the pattern thus obtained. (12 Dec 1998) |
| spectroscopy, mossbauer | A spectroscopic technique which uses the mossbauer effect (inelastic scattering of gamma radiation resulting from interaction with heavy nuclei) to monitor the small variations in the interaction between an atomic nucleus and its environment. Such variations may be induced by changes in temperature, pressure, chemical state, molecular conformation, molecular interaction, or physical site. It is particularly useful for studies of structure-activity relationship in metalloproteins, mobility of heavy metals, and the state of whole tissue and cell membranes. (12 Dec 1998) |
| spectroscopy, near-infrared | A noninvasive technique that uses the differential absorption properties of haemoglobin and myoglobin to evaluate tissue oxygenation and indirectly can measure regional haemodynamics and blood flow. Near-infrared light (nir) can propagate through tissues and at particular wavelengths is differentially absorbed by oxgenated vs. Deoxygenated forms of haemoglobin and myoglobin. Illumination of intact tissue with nir allows qualitative assessment of changes in the tissue concentration of these molecules. The analysis is also used to determine body composition.

| spectrum | A charted band of wavelengths of electromagnetic vibrations obtained by refraction and diffraction. By extension, a measurable range of activity, such as the range of bacteria affected by an antibiotic (antibacterial spectrum) or the complete range of manifestations of a disease. (18 Nov 1997) |
| spectrum analysis | The measurement of the amplitude of the components of a complex waveform throughout the frequency range of the waveform. (12 Dec 1998) |
| spectrum analysis, mass | Analysis of the mass of an object through means of determining the wave length(s) at which electromagnetic energy is absorbed by that object. (12 Dec 1998) |
| spectrum analysis, raman | Analysis of the intensity of raman scattering of monochromatic light as a function of frequency of the scattered light. (12 Dec 1998) |

A spectrometer is an optical instrument for measuring properties of light over some portion of the electromagnetic spectrum. The measured variable is often the light intensity but could also be the polarization state, for instance. ...

The Sinclair ZX Spectrum was a small home computer released in the United Kingdom in 1982 by Sinclair Research. Based on a Zilog Z80 CPU running at 3.50 MHz, the Spectrum came with either 16 KB or 48 KB of RAM (an expansion pack was also available to upgrade the former). The hardware designer was Richard Altwasser of Sinclair Research and the software was written by Steve Vickers (on contract from Nine Tiles Ltd, the authors of Sinclair BASIC). ...
