# 3D Molecular Orientation

## Appears In

                        - Molecules Have an Orientation, and Scientists Have a New Way to Measure It
                        - National Institute of Standards and Technology

To advance materials science, researchers at NIST have developed a new way to measure the 3D orientation of molecules within a material made of components called polymers. In this illustration, the pinlike forms represent polymer chains, with the color indicating average angle off the vertical plane and the size of the pinhead representing the distribution of orientations around that average. The image in the background shows the raw data, which is produced by a method known as broadband coherent anti-Stokes Raman scattering, or BCARS.
