An infrared spectroscopic study of CO on Cu(111): The linear, bridging and physisorbed species

Vibrational linewidths of adsorbed molecules: Experimental considerations and results

“…This process can be regarded [17] as an extreme case of de-20 phasing involving motion parallel to the surface. Very similar effects have also been observed [8] for CO on Cu(111).…”

“…The natural linewidth of the same vibration in the gas 2 phase is some 1010 times smaller. In recent years, the study of these linewidths has been an area of intense experimental [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and theoretical [3 ,17-43] interest. Nevertheless, a clear understanding of the important line-broadening mechanisms is only beginning to emerge.…”

AC microcalorimetry of adsorbates on evaporated metal films: Orientational ordering of H₂ multilayers

“…The theory of finite-size effects in firstorder transitions has recently attracted considerable attention. 1 ' 1 [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20] Agreement with theory has been demonstrated in both simulations 16 and experiments.l 8 -20 However, there are few experimental studies in this area.…”

Infrared Reflection Absorption Study for Carbon Monoxide Adsorption on Chromium Deposited Cu(100) Surfaces

“…Infrared reflection spectroscopy (IRRAS) is a powerful tool to study adsorption of simple molecules onto well-defined metal surfaces: its high sensitivity to adsorption sites and metal/molecule interactions supports investigation of metal and alloy surfaces' chemical properties. [20][21][22][23][24][25][26] Indeed, the authors have previously reported IRRAS spectra for carbon monoxide (CO) adsorption on several bimetallic surfaces having periodic atomic structures. [27][28][29][30][31] The results indicate that CO is useful as a probe for exploration of surface lattice structures of bimetallic alloys.…”
