En la zona del espectro electromagnético IR con longitudes de onda comprendidas entre 1300 y 400 cm1 (infrarrojo lejano), la asignación de las bandas de absorción a vibraciones moleculares es más difícil de realizar, debido a que cada una de ellas está generada por absorciones individuales sumadas (multiplicidad de las bandas).
19/11/2018· Un sensor de CO2 es un instrumento que se utiliza para la medición de gas de dióxido de carbono en un ambiente determinado. Habitualmente estos aparatos registran el dióxido de carbono en partes por millón (ppm) en los espacios ocupados y nos ofrecen una muestra de la concentración de este gas en el aire que respiramos.
Carbon Dioxide, CO 2 Fortunatly HCl is not present in high concentrations and it does not absorb very strongly. CO 2, however, is present at higher concentrations and it absorbs strongly in the CO 2 has more than two atoms, it can vibrate several different ways. These different types of motion occur at different frequencies.
Carbon dioxide absorbs infrared radiation (IR) in three narrow bands of wavelengths, which are , and 15 micrometers (µM). This means that most of the heat producing radiation escapes it. About 8% of the available black body radiation is picked up by these "fingerprint" frequencies of CO2.

The IR Spectrum Table is a chart for use during infrared spectroscopy. The table lists IR spectroscopy frequency ranges, appearance of the vibration and absorptions for functional groups. There are two tables grouped by frequency range and compound class.
Messungen von Kohlendioxid (CO2) werden in vielen Anwendungen benötigt: von Gebäudeautomation über Gewächshäuser bis hin zur Biowissenschaft und Sicherheit. Erfahren Sie, warum CO2Sensoren von Vaisala einzigartig sind.
The Telaire T6743 Internal CO2 Sensor is a nondispersive infrared (NDIR) CO2 sensor that implements a single channel diffusion sampling method for automotive HVAC applications, including automatic fresh air control and safety sensing for CO2 refrigerants. Along with the patented ABC Logic™ lifetime calibration warranty, its low power ...
Carbon Dioxide is composed of a single carbon atom covalently bonded to an oxygen atom on either side. This structure allows for CO 2 to have many vibrational and rotational states, making it an effective greenhouse gas. It is able to absorb many wavelengths of light and energy emitted by the earth and transform this into thermal energy.
