DATAFILE: Al(CH3)3_Okabe(1991)_298K_184-227nm.txt
NAME: trimethylaluminium, TMAl
FORMULA: Al(CH3)3
AUTHOR(YEAR): Okabe(1991)
T: 298K
λ: 184-227nm
BIBLIOGRAPHY: H. Okabe, M.K. Emadi-Babaki, and V.R. McCrary, "Temperature-dependent ultraviolet absorption spectra of group IIIb and Vb compounds used in photo-assisted chemical vapor deposition", J. Appl. Phys., 69, 1730-1735 (1991) DOI: 10.1063/1.347219
COMMENTS: The UV absorption spectrum was measured several times by a Cary 2390 (Varian) spectrophotometer with a bandwidth of 2 nm

Al(CH)3 is almost 100% dimer at room temperature and dissociates into monomers at higher temperatures, reaching to almost 100% monomer below 1 Torr and above 423 K

The absorption spectrum shown in Fig. 3 has been digitized
