We built a transient absorption spectrophotometer that can determine transient absorption spectral changes that occur at times as fast as approximately 200 ns and as slow as a minute. The transient absorption can be induced by a temperature-jump (T-jump) or by optical pumping from the deep ultraviolet (UV) to the infrared (IR) by use of single ns Nd:YAG laser pulses. Our use of a fiber-optic sp...

The total ozone measurements by Belsk’s Dobson spectrophotometer have been compared with the satellite total ozone taken during the OMI (on board of Aura spacecraft) overpasses for the period August 2004 – July 2006. The agreement between both data sets is much better if the results of the recent (June 2005) calibration campaign of Belsk’s Dobson at Hohenpeissenberg are incorporated to the stan...

In the present data article, fluoride concentration levels of drinking water (with spring or groundwater sources) in 10 villages of Asara area located in Alborz province were determined by the standard SPADNS method using a spectrophotometer (DR/2000 Spectrophotometer, USA). Daily fluoride intakes were also calculated based on daily drinking water consumption. The fluoride content were compared...
