In intrinsic configuration, SERS signals from the targets are measured. The targets can be monitored by relative intensity changes in the spectrum caused by targets

In inverse photoemission, or IPE, an incident electron is temporarily trapped in an unoccupied molecular orbital typically several eV above the Fermi edge, from where it can decay to an low-lying empty orbital by photon emission.

In inverted chemical force microscopy the pull-offforces of a reactant-covered AFM tip are measured in situ during the conversion of the reactive groups. The interaction between tip and inert surface varies with the extent of the reaction. The approach is depicted schematically for the reaction of ester groups to hydroxyl groups in aqueous NaOH.

In is employed. After photodetachment of the electron, dissociation will occur equally in the two possible channels

In is shown the calculated results for the paramagnetic fee FeCo alloy over the whole concentration range, as well as experimental values and one point of the paramagnetic ordered B2 structure.

In is shown the resistivity as a function of

In is the semilog plot of the same function.

In isoconversional methods a single-step rate equation is applied to a narrow temperature region AT that changes with the extent of conversion adapted fromVyazovkin and Sbirrazzuoli with permission of Wiley-VCHj.

In Kadanoff s construction the spin lattice .

In KAg4l5 sample.

In large liver metastases uptake of MAA and microspheres is often confined to the tumor rim. The lesions present with a shell of high vascularity but, due to rapid tumor growth, the blood supply within the metastases is diminished. The horizontal line profile demonstrates that uptake within the inner tumor portions may be as low as in the normal liver. Thus tumoricidal doses might not be achieved in areas with borderline perfusion still containing viable tumor cells

In large systems that require explicit representation, understanding bond-making -bond-breaking processes can often be accomplished using a quantum mechanical representation of only a portion of the full system, with a molecular mechanics representation of the rest

In larger plants, the plant engineering function is often divided into departments to serve particular needs

In later experiments performed using a thicker silica disc, the 1535 cm 1 absorption remained for 24 hrs after admitting ethylene at 3 atm and 45 C. This could be an indication that not all the 7r-allyl groups were involved in the polymerization or merely that diffusion of the ethylene through the silica and or polyethylene was slow.

In linear vibration welding every point on the moving part forms a small orbit around a fixed point on the stationary part.

In lliis cross section of a two-cycle engine, only a trained eye can identify the engine porting that distinguishes it from a four-cycle engine.

In long-term conditions, local rock falls repeatedly occur in the ridges, heavily fractured by

In longitudinally heated furnaces

In low energy electron diffraction, LEED, electrons with energies between 10 eV and 1000 eV yields sharp diffraction beams which give rise to characteristic diffraction patterns. The LEED pattern shown on the right side has been recorded for

In LPC synthesis, analysis frames are read sequentiaiiy and the aigorithm has to decide whether the stimulation should be a noise signal or a pulse stream

In LSIMS and FAB, sample-matrix cluster ion formation and desolvation processes occur on a longer time scale. Adapted from Ref. by permission. John Wiley Sons, 1995.

In lysozyme the glycosidic bond is cleaved by acid-base-catalyzed hydrolysis. They gray area is the active center see

In Lyuborsky and colleagues work,15 it was demonstrated that oxygen is consumed in

In m academic institution, the operations vice president would be the provost md die major

In many metals each atom is surrounded by 12 nearest neighbors
