In Situ Kinetics of Self-Assembly by Surface Plasmon Resonance Spectroscopy Kevin A. Peterlinz† and R. Georgiadis*,† Department of Chemistry, The George Washington University, Washington, D.C. 20052, and Department of Chemistry, Boston University, Boston, Massachusetts 02215 Received October 9, 1995. In Final Form: June 5, 1996X Using surface plasmon resonance (SPR) spectroscopy in the Kretschmann configuration, we followed the self-assembly of organic ultrathin films which resulted from exposure of gold surfaces to solutions of CH3(CH2)n-1SH (n ) 8, 12, 16, and 18) in ethanol and heptane. We monitored film growth in situ and continuously for up to 72 h with an overall thickness resolution of
