TL;DR: In this article, the structure of acetylene adsorbed on Pd(111) below ∼ 200 K was probed using near-edge X-ray absorption fine structure (NEXAFS) and ultraviolet and Xray photoelectron spectroscopy.

TL;DR: The surface species formed following acetylene adsorption on Pd(111) at 300 K is identified as a vinylidene as discussed by the authors, which is consistent with previous photoelectron and high-resolution electron energy loss spectroscopy data.

TL;DR: Polarisation-dependent NEXAFS data are presented for the reaction intermediate C4H4 chemisorbed on Pd(111) in this article, which indicates that this species is a metallocycle with slightly expanded ( ~ 0.05 A) C-C bonds.

TL;DR: The chemistry of ethylene on a clean Mo(100) surface is scrutinized using an array of surface-sensitive techniques including synchrotron-radiation-generated angle-resolved ultraviolet photoelectron spectroscopy and Auger and thermal desorption spectroscopies.

TL;DR: In this article, angle-resolved ultraviolet photoelectron spectroscopy was used to identify two surface species after adsorbing acetylene at 80 K. One species is undistorted chemisorbed acetylene, the other is an acetylenic species which is rehybridized to approximately sp 2 and is adsorbed with its C-C axis oriented at ∼ 45° with respect to the surface normal.
