TI  - ToF-SIMS imaging of molecular-level alteration mechanisms in Le Bonheur de vivre 
      by Henri Matisse.
PG  - 1015-1030
AB  - Time-of-flight secondary ion mass spectrometry (ToF-SIMS) has recently been shown 
      to be a valuable tool for cultural heritage studies, especially when used in 
      conjunction with established analytical techniques in the field. The ability of 
      ToF-SIMS to simultaneously image inorganic and organic species within a paint 
      cross section at micrometer-level spatial resolution makes it a uniquely 
      qualified analytical technique to aid in further understanding the processes of 
      pigment and binder alteration, as well as pigment-binder interactions. In this 
      study, ToF-SIMS was used to detect and image both molecular and elemental species 
      related to CdS pigment and binding medium alteration on the painting Le Bonheur 
      de vivre (1905-1906, The Barnes Foundation) by Henri Matisse. Three categories of 
      inorganic and organic components were found throughout Le Bonheur de vivre and 
      co-localized in cross-sectional samples using high spatial resolution ToF-SIMS 
      analysis: (1) species relating to the preparation and photo-induced oxidation of 
      CdS yellow pigments (2) varying amounts of long-chain fatty acids present in both 
      the paint and primary ground layer and (3) specific amino acid fragments, 
      possibly relating to the painting's complex restoration history. ToF-SIMS's 
      ability to discern both organic and inorganic species via cross-sectional imaging 
      was used to compare samples collected from Le Bonheur de vivre to artificially 
      aged reference paints in an effort to gather mechanistic information relating to 
      alteration processes that have been previously explored using muXANES, SR-muXRF, 
      SEM-EDX, and SR-FTIR. The relatively high sensitivity offered by ToF-SIMS imaging 
      coupled to the high spatial resolution allowed for the positive identification of 
      degradation products (such as cadmium oxalate) in specific paint regions that 
      have before been unobserved. The imaging of organic materials has provided an 
      insight into the extent of destruction of the original binding medium, as well as 
      identifying unexpected organic materials in specific paint layers.
