The method of Fourier transform spectroscopy can also be used for absorption spectroscopy. The primary example is  FTIR Spectroscopy , a common technique in chemistry.rom Wikipedia, the free encyclopedia. Fourier transform spectroscopy is a measurement technique whereby spectra are collected based on measurements of the coherence of a radiative source, using time-domain or space-domain measurements of the electromagnetic radiation or other type of radiation.
Currently has same time zone offset as GMT (UTC +0:00) but different time zone name. Greenwich Mean Time (GMT) has no offset from Coordinated Universal Time (UTC) . This time zone is a standard time zone and is used in: Europe, Africa, North America, Antarctica. This time zone is often called Greenwich Mean Time. See full time zone map.
Greenwich Mean Time (GMT) is the mean solar time at the Royal Observatory in Greenwich, London.GMT was formerly used as the international civil time standard, now superseded in that function by Coordinated Universal Time (UTC) .oon GMT is the annual average (i.e., mean) moment of this event, which accounts for the word mean in Greenwich Mean Time. Originally, astronomers considered a GMT day to start at noon while for almost everyone else it started at midnight.
