Photodissociation Dynamics of Formic Acid at 206 nm
The photodissociation dynamics of formic acid (HCOOH) at 206 nm have been investigated from rotationally resolved laser induced fluorescence spectra of OH (Π) fragments produced exclusively in the ground state. From the spectra, the rotational energy of the fragments was measured to be 820 ± 50 cm−1. The translational energy released in the products, which is 87% of the total available energy o...
متن کاملA deep-UV optical frequency comb at 205 nm.
By frequency quadrupling a picosecond pulse train from a Ti:sapphire laser at 820 nm we generate a frequency comb at 205 nm with nearly bandwidth-limited pulses. The nonlinear frequency conversion is accomplished by two successive frequency doubling stages that take place in resonant cavities that are matched to the pulse repetition rate of 82 MHz. This allows for an overall efficiency of 4.5 %...
متن کاملDetermination of fumaric acid in apple juice by on-line coupled capillary isotachophoresis-capillary zone electrophoresis with UV detection.
An on-line coupled capillary isotachophoresis-capillary zone electrophoresis (cITP-CZE) method for the determination of the fumaric acid content in apple juice is presented. A clear separation of fumaric acid in real samples is achieved within 20 min. The leading, terminating and background electrolyte of the employed system consist of 10 mM HCl+beta-alanine+5 mM beta-cyclodextrin+0.05% hydroxy...
