Recent studies have demonstrated that functionalized portions of long-chain hydrocarbons (CH3(CH2)nX, where X = SH, S, SS, NH2, Br, I) physisorbed on graphite at the liquid−solid interface exhibit enhanced contrast (increased tunneling current) whe

Investigations of long-chain hydrocarbon and substituted hydrocarbon materials physisorbed at the liquid−solid interface have provided a particularly fruitful area of investigation for the scanning tunneling microscope (STM). Studies of this kind p

Monolayer films of several primary substituted hydrocarbons CH3(CH2)nCH2X (X = CH3, OH, NH2, SH, Cl, Br, I; n = 16−30) have been imaged on graphite at the solution−substrate interface using a scanning tunneling microscope (STM). The straight chai

The negative ion zero electron kinetic energy (ZEKE) spectrum of I[sup [minus]]-CH[sub 3]I is presented and discussed. In addition to the high-frequency vibrational structure previously seen in the photoelectron spectrum (PES) of I[sup [minus]]CH[sub

We describe the reaction dynamics which occur upon excitation of the I−⋅CH3I ion–molecule complex to the first optically allowed excited electronic state. Photoelectron spectroscopy of I−⋅CH3I confirms the identification of the species as e

The I−⋅CH3I and I−⋅CD3I intermediates in the gas‐phase SN2 identity reaction, I−+CH3I→CH3I+I−, are isolated, cooled in a free jet, and characterized using negative ion photoelectron spectroscopy. The spectra appear similar to bare I

Photoelectron spectra of the I−⋅CH3I, I−⋅CH3Br, and I−⋅CH2Br2 complexes each display a relatively sharp main feature shifted from that of I− by the expected binding energies of the ion–dipole bound negative ions. We observe narrow pho

We report a rapid increase in the propensity of D 2 O molecules to incorporate into (H 2 O) − n clusters upon collisions between D 2 O and a distribution of (H 2 O − n , 6 n n 2 O) − n distribution are discussed.
