“…55 Moreover, relatively simple atomic superstructures could also be refined with high accuracy, examples comprise hydrogen on Ir(110), 56 (R P = 0.10) and halogens on metal surfaces such as Cl/Ru(0001) 57 and Br/Pt(110) 58 with R P = 0.19 and 0.23, respectively. LEED structure refinement was also successfully carried out for sulphide or oxide adlayers like O/V(110), 59 MnO/Ag(100), 60 S/Ir(100), 61 O/Pt/Cu(100), 62 V 2 O 3 /Pd(111), 63 S/Au(110), 64 O/ Cu(210), 65 resulting in R P of 0.11-0.36. Excellent R P values of around 0.15-0.22 were also obtained for smaller organic adsorbates such as dinitrogen/NaCl(100), 7 carbon monoxide/ Pt(110), 8 formic acid/TiO 2 (110), 9 cyanide/Ni(110), 10 and glycine/ Cu(110).…”
