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.
Central Standard Time is the Central Time Zone of the United States of America (USA). Central Standard Time (CST) is 6 hours behind Greenwich Mean Time (GMT-6).n most states in the USA and in most provinces in Canada, Daylight-Saving Time (DST) is observed. During DST CT (or CDT) is 5 hours behind Greenwich Mean Time (GMT-5). After the Summer months Central Time is shifted back by 1 hour to US Central Standard Time (CST) or (GMT-6).
