Abstract
One embodiment relates to a method for determining a concentration of a molecular species of interest. In this method, electromagnetic radiation is transmitted into a volume of gas within an output exhaust system. The transmitted electromagnetic radiation has a first intensity at a characteristic frequency that is associated with a transition of the molecular species of interest. Electromagnetic radiation is then received from the volume of gas at a second intensity. The method then correlates the first intensity to the second intensity to determine the concentration of the molecular species of interest within the volume of gas. Other methods and systems are also disclosed.
