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.
GMT is now a Time Zone. Until 1972, Greenwich Mean Time (also known as Zulu time) was the same as Universal Time (UT). The difference between GMT and UTC. Since then, GMT is no longer a time standard. Today, Greenwich Mean Time is only the name of a time zone that is used by a few countries in Africa and Western Europe, including the UK during winter and all year in Iceland.
