WebNewman Projection Assessment. NPA. OVERVIEW. EVIDENCE. REVIEW. VERSIONS. CITATIONS. Listed below is general information about the instrument. Summary. WebA Fischer projection is a way of showing a three dimensional structure in two dimensions. It shows the absolute configuration at chiral centres. In a Fischer projection, the longest chain is drawn vertically. The four bonds to a chiral carbon make a cross, with the carbon atom at the intersection of the horizontal and vertical lines.
