Infrared spectrum of matrix isolated tricarbonyliron

Time-resolved infrared diode laser spectroscopy of the ν3 band of the jet-cooled Fe(CO)2 radical produced by ultraviolet photolysis of Fe(CO)5

“…Infrared spectra of Fe͑CO͒ 5 photofragments in low temperature matrices have been studied by Poliakoff and Turner 1 and Poliakoff. 2 They tentatively assigned an absorption at 1876 cm Ϫ1 to Fe͑CO͒ 2 or FeCO. Peden et al 3 identified a peak at 1860 cm Ϫ1 , observed in a low temperature matrix upon cocondensation of atomic iron with the noble gas/CO mixture, as due to Fe͑CO͒ 2 .…”

“…Extensive kinetic as well as spectroscopic studies have been carried out on these radicals. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Considerable theoretical works have also been published. [18][19][20][21][22][23] As for the FeCO radical, for example, it has been shown by a recent photodetachment study of the FeCO Ϫ anion 13 that the ground electronic state is of 3 ⌺ Ϫ symmetry and that the 5 ⌺ Ϫ excited electronic state is located only 3.24Ϯ0.07 kcal/mol above the ground state.…”

Adsorption and Decomposition of Iron Pentacarbonyl on Y Zeolites

“…15,[22][23][24]. The present IR results for From the partly reversible hydroxyl interaction with the complex in HY, it is estimated that about one quart of the iron is oxidized during decomposition.…”

Raman spectroscopic study of iron pentacarbonyl on silver at elevated temperatures

“…Vaporized Fe(CO) 5 was introduced into a vacuum cell [5 ] 10~8 Torr (1 Torr \ 133.3 Pa)] and its pressure was monitored with a capacitance manometer. A beam of radiation at 514.5 nm from an argon ion laser (Spectra-Physics Model 2016) was used as the Raman exciting source.…”
