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.
UTC+5h or GMT +5h would refer to that time zone being five hours ahead of UTC of GMT and so forth for the other time zones. The usage of UTC and GMT is based upon a twenty four hour clock, similar to military time, and is based upon the 0 longitude meridian, referred to as the Greenwich meridian in Greenwich, England.
