Pixel Imaging Mass Spectrometry with fast and intelligent Pixel detectors
We report on `proof of concept' experiments in Pixel Imaging Mass Spectrometry (PImMS) using an ultra-fast frame-transfer CCD camera and also describe an intelligent CMOS sensor which is being
Velocity map imaging in time of flight mass spectrometry.
A new variation on time of flight mass spectrometry is presented, which uses a fast framing charge coupled device camera to velocity map image multiple product masses in a single acquisition. The
Pixel imaging mass spectrometry with fast silicon detectors
Abstract We report on ‘proof of concept’ experiments in pixel imaging mass spectrometry (PImMS) using an ultra-fast frame-transfer CCD camera. The fast framing CCD camera is capable of recording and
The photodissociation dynamics of ozone at 226 and 248 nm: O(3PJ) atomic angular momentum polarization.
Speed distributions, spatial anisotropy parameters, spin-orbit populations and polarization data each lend support to the assignment of the major pathway to curve crossing from the B to the repulsive R surface, generating fast fragments in a wide range of vibrational states.
Application of fast sensors to microscope mode spatial imaging mass spectrometry
The application of fast detectors to microscope mode spatial imaging mass spectrometry, in which the two-dimensional distributions of particular ion masses over a sample are projected onto a
The ultraviolet photodissociation of CS2: the S(1D2) channel.
It is proposed that dissociation below the barrier to linearity occurs primarily on a surface with a significant potential energy well and without an exit channel barrier, such as that for the ground electronic state.
A complete quantum mechanical study of chlorine photodissociation.
The calculations rigorously confirm the currently accepted mechanism for the UV photodissociation of Cl(2), in which the majority of the products exit on the C(1)Π(1u) state, with non-adiabatic couplings to the A(3) Ω = 1 states, and a small contribution from the B(3]Π state present at longer wavelengths.
Electronic polarization effects in the photodissociation of Cl2.
Good agreement is found between the recent theory and the measurements made here, which include the first experimental determination of high rank K = 3 orientation, predicted to be important for dissociation into both asymptotic product channels.
The vibrationally mediated photodissociation of Cl2.
The photodissociation of vibrationally excited Cl(2)(v = 1) has been investigated experimentally using the velocity mapped ion imaging technique and it was found that there was negligible cooling of the vibrational degree of freedom of the parent molecule in the molecular beam.
