No, a molecule does not have the same extinction coefficient at all wavelengths. The extinction coefficient varies across different wavelengths because different wavelengths of light interact with the molecule in different ways, leading to varying levels of absorption and scattering.

What is the extinction coefficient of porphyrins?

The extinction coefficient of porphyrins depends on the specific type of porphyrin molecule and the wavelength of light being used for measurement. It typically falls in the range of 20,000 to 150,000 M^-1cm^-1 at the Soret band (around 400 nm) and 5,000 to 50,000 M^-1cm^-1 at the Q bands (around 500-700 nm).


What is the molar extinction coefficient for glucose at 510 nm?

I am not some one of this background and so please correct me if I am wrong. I think molar extinction coefficient will be very less and according to molecular structure of any molecule (bond vibration etc..,) only some wavelengths will have reasonable absorption and for glucose those wavelenghts are 1550-1850 nm; 6450-5400 cm(-1) (first overtone) 2000-2500 nm; 4000-5000 cm(-1) (combination). These are the spectral windows in which glucose has significant absorption.


What is the coefficient of oxygen from P O2 to P2O3?

The coefficient of oxygen in the reaction P + O2 → P2O3 is 1. This means that one molecule of oxygen (O2) reacts with one molecule of phosphorus (P) to form one molecule of phosphorus oxide (P2O3).


A molecule that contains atoms enabling it to reflect light is called a pigment?

Actually, a pigment is a molecule that selectively absorbs certain wavelengths of light, resulting in the perception of color by reflecting or transmitting other wavelengths. Pigments are responsible for the color of many living organisms, including plants, animals, and microorganisms.


What coefficient does HCl have in the following balanced equation CaCl2 plus H2CO3CaCO3 plus HCl?

The coefficient of HCl in the balanced equation is 2. This is because the balanced equation shows that 1 molecule of CaCl2 reacts with 1 molecule of H2CO3 to form 1 molecule of CaCO3 and 2 molecules of HCl.

Why the coefficient of volume expansion of the water different with coefficient of volume expansion of the ethanol?

Since there is extensive hydrogen bonding in case of water (two -OH per molecule) unlike ethanol (which has one -OH per molecule) so the intermolecular force difference is there between water and ethanol. Thus the coefficient of volumetric expansion will also be different, 'coz intermolecular force is a direct variable effecting this coefficient......

How is it possible for a single electron to produce so many different wavelengths and frequencies?

A single electron can produce different types of radiation. Radiation, frequency, and wavelength all rely on each other. If an electron can produce multiple types of radiation, it can also produce different wavelengths and frequencies, because the wavelengths and frequencies are dependent on the radiation type.

Can partition coefficient influence passive diffusion rate?

Yes, the partition coefficient can influence passive diffusion rate by determining how easily a molecule can move across a membrane. A higher partition coefficient typically means the molecule is more likely to dissolve in the lipid bilayer of the membrane, thus facilitating faster passive diffusion. Conversely, a lower partition coefficient can slow down passive diffusion.


In the reaction Mg plus Cl2 - MgCl2 .What should be the coefficient for Cl2?

The coefficient for Cl2 should be 1 in order for the reaction to be balanced. This means there should be 1 molecule of Cl2 reacting with 1 atom of Mg to form 1 molecule of MgCl2.


What is fluorescence tagging?

Fluorescence tagging is a technique that involves attaching a fluorescent molecule to a target molecule, such as a protein or DNA, to enable visualization and tracking of the target molecule within cells or tissues. When illuminated with specific wavelengths of light, the fluorescent tag emits light of a different color, allowing researchers to study the location and movement of the tagged molecule in biological systems.


What is infra red spectra stretching?

In molecules, there are bonds. When they are exposed to infra-red radiation, different bonds absorb the infra-red radiation at different wavelengths. In the observed spectrum, there are "bond stretches", where the observed intensity of certain wavelengths drops due to the absorption. By comparing these "stretches" with a data-booklet, you can see which bonds the molecules have. This is called Infra-red Spectroscopy.
