It is also used for the elucidation of biochemical signaling pathways. The analysis techniques are those of phytochemistry&colon; extraction, isolation, structural elucidation, then quantification. CI mass spectrometry is a useful tool in structure elucidation of organic compounds. The elucidation of cuneiform led to the decipherment of Sumerian. This insight provided early elucidation of the nature of the genetic code. His work "ruh al-Bayan" (the Spirit of Elucidation) is a voluminous exegesis. Structural elucidation by X-ray crystallography was completed in 1960. Early studies lacked sufficient resolution for further elucidation of this group. At mid-century, the instrumental revolution necessitated a new approach to structural elucidation. CI has several important applications in identification, structure elucidation and quantitation of organic compounds. Macrophages - their use in elucidation of cytoskeletal roles of actin. As such C NMR is an important tool in chemical structure elucidation in organic chemistry. Isotope peaks within a spectrum can help in structure elucidation. Teller made valuable contributions to bomb research, especially in the elucidation of the implosion mechanism. Further elucidation of his theory was never found in his writings.
