anilineultrafastfemtosecondmolecular dissociationIn this work we investigate the interaction of aniline in the gas phase with 50 fs pulses of radiation at a wavelength of 800 nm. Ion yields were measured using a reflectron time-of-flight mass spectrometer that avoids spatial averaging by collecting ...

The final mass of ZrO2 was normalized to 100% (remaining weight at 600 °C). The weight of ideal UiO-66 at 350 °C is 220.2% which agrees with the chemical formula of Zr6O6(BDC)6, In contrast, the weight of defective UiO-66 at 350 °C is below 220.2% suggesting the defic...
Low-energy mass spectrometry and chromato-mass spectrometry have been used to show that major final products of the pyrolysis of tetrakis(trifluoromethyl) allene (TTA) are perfluoro-1,3-cyclopentadiene and hexafluoroethane, formed as a result of the thermal loss of two trifluoromethyl radicals. This...
12. The molar mass of aniline is 93 g/mol. What is its molecular formula? 13. Calculate the mass percent of carbon, nitrogen and oxygen in acetamide, C 2 H 5 NO. 14. A 50.51 g sample of a compound made from phosphorus and chlorine is decomposed. Analysis of the products showed that...
pyramid, unlike the 3-isomer whose amino configuration resembles that of aniline 〈75JCS(F2)438〉. The computed (ab initio SCF MO calculation) barrier heights to inversion of 7.6, 8.8, 8.8 and 11.4 kJ mol−1 for the 4-, 3- and 2-isomers and aniline respectively are higher t...
FD-1080, with a small molecular mass of 760 Da, was capable of fast kidney metabolism and presented an absorption and emission peak at 1,064 nm and 1,080 nm, respectively. The fluorescence QY of FD-1080 was 0.31% in ethanol. After encapsulation by FBS to form a complex, the ...
The present work introduces a detailed molecular-level mechanism of the formation of MIL-53(Al), unraveled by combining in situ time-resolved high-resolution mass-spectrometry, magic angle spinning nuclear magnetic resonance spectroscopy and X-ray diffraction. In contrast to the general belief, the ...
