![]() ![]() The signal intensity remains constant until the delivery of a high-energy pulse (from a pulse source), initiating photolysis/radiolysis of the sample. The intensity of a selected wavelength of light is monitored by a fast photodetector. A beam of analytical light that continuously passes through the sample is split on a monochromator or passes through a narrow bandpass filter. The operational principles of this technique are depicted in Fig. At the INCT, both LFP and PR operate with transient digitizer UV–VIS–NIR spectrophotometric detection. Moreover, they can use transient digitizer or pump(pulse)–probe data collection systems. Several other similar facilities are available in China, India, Japan, and the USA.īoth LFP and PR may operate with various detections systems, such as ultraviolet–visible–near infrared (UV–VIS–NIR) or infrared (IR) spectrophotometry, Raman spectroscopy, conductometry, electron paramagnetic resonance (EPR), nuclear magnetic resonance (NMR), light scattering (LS), etc. In Europe, one more picosecond PR facility is available in France. Both systems work with nanosecond time resolution. For instance, two PR systems are available in Poland: the first one, at the Institute of Nuclear Chemistry and Technology in Warsaw (INCT) and the second, at the Institute of Applied Chemistry and Technology in Lodz. LFP systems are quite common in scientific laboratories, whereas PR facilities are rather limited. Therefore, it is very convenient to have LFP and PR available at one laboratory. Complete explanation of the observed changes in the investigated systems very often requires combined results from both techniques. This has been demonstrated many times in literature. It is important to note that both the techniques, i.e., LFP and PR, are considered complementary techniques. Interest in these methods grew considerably as the practical applications expanded from chemistry to biology, materials science, environmental sciences, etc. Currently, even attosecond-level time resolution systems are available. Within years, these techniques became more powerful and sophisticated due to the developments in electronics and optics. The first investigations applying LFP systems were published several years later. The PR technique was introduced in 1960 simultaneously by several independent researchers form different scientific centers. They jointly won the Nobel Prize in Chemistry in 1967 for this invention. The first flash photolysis system with millisecond time resolution was introduced to scientists by Norrish and Porter in 1949 and Porter in 1950. The operating principles of both techniques inherited the idea from flash photolysis.
