A simple, easily constructed in situ X-ray absorption spectroelectrochemica
l cell is described. Its capabilities for acquiring good quality, reproduci
ble X-ray absorption spectra in the transmission, fluorescence and energy d
ispersive modes, in tandem with standard electrochemical measurements, are
demonstrated using electrodeposited nickel hydroxide films. (C) 1999 Elsevi
