โฆ Synopsis
We reexamined the protonic locations in the phase of hydrogen molybdenum bronze (H 0.26 MoO 3 ) with the lowest hydrogen content by lineshape analysis using a computer simulation, in which we dealt with systems containing more than three protons. NMR spectra were simulated for various models with a variety of protonic arrangements and linear combinations of the models were tested for whether they could reproduce observed spectra. Spectra for the six-proton cluster models, which were suggested for H 0.33 MoO 3 by Adams et al. (Acta Crystallogr. Sect. B 49, 958 (1993)), were also simulated. Then, it was suggested that 3-to 5-proton clusters existed in the bronze.

Hydrogen molybdenum bronzes H x MoO 3 (0< x < 2) are consistently described as low-dimensional mixed conductors, whose properties under ambient conditions are controlled by charge density wave modulations. Proton conduction pathways in the bronzes are modeled by a bond valence approach. The redistri
