Hey to all.. I am in the process of designing a ligand for a clarinet mouthpiece for my own use created only out of string material (braided kevlar). For those uninformed (like me a few weeks ago) saxophone/clarinets are instruments where the vibration of the standing wave through the...

Ammonia is present in the spectrochemical series near the middle, just after water. Is it a strong field ligand, or a weak field ligand? Also, take into consideration the complex ##[Ni(NH_3)_4 Cl_2]##. Chloride ion is towards the left end of the spectrochemical series which means it is a weak...

I have a lab report for an experiment in which we used ion exchange chromatography to separate three Chromium complexes, CrCl2(OH2)4+, CrCl(OH2)52+, and Cr(OH2)63+ We used a UV vis to find the absorbance of each compound and used that to calculate the mole fraction of each ion in a mixture. One...

Copper (ii) chloride is a light brown solid, which slowly absorbs moisture to form a blue-green dihydrate. According to ligand field theory, water is a stronger field ligand than chloride. As a result, the dihydrate form should have a larger d orbital splitting than the anhydrous form. Thus...

I want to exchange my Au-citrate nanoparticle with two kinds of ligands :PEG-COOH and PEG-OH. Which one is suppose to have more anionic charge density.

I've been introduced to ligand-field theory lately and was then wondering what roles f orbitals play in the magnetic properties of elements and alloys. Apparently f orbitals behave oddly in that they hybridize in weird ways because they're so large and that the crystal field actually affects the...

Hi everyone, I'm working with quantum dot (PbS). However, I'm actually not a chemist, so could anyone help me to address some issues regarding quantum dots especially related to ligand exchange process. My questions are: 1. anyone can address about what kind of functionality (e.g: thiol...

Are ALL ligand exchange reactions reversible? Therefore, if the Kstab of one complex is LESS than that of the other complex, would it ONLY be possible to form the LESS stable complex by 'flooding' the mixture with the appropriate ion. (these values are not real but they illustrate what I...

the following?: low-spin d5 metal. Energy = -2Δ -4K (where K is exchange energy. i,e. minimization of energy due to parallel spins) low-spin d6 metal. Energy = -1.6Δ -3K Therefore: energy needed to add an electron = ΔE= 0.4Δ + K Is that correct? maybe I should be talking about...

"In chemical signaling, adaptation enables cells to respond to changes in the concentration of a signaling ligand (rather than to the absolute concentration of the ligand) over a very wide range of ligand concentrations. The general principle is one of a negative feedback that operates with a...

Hi guys, i know how to name monodentate ligand complexes but there is a particular one that my textbook and teacher's notes is quite the opposite, its regarding the fac and mer isomer. for a Ma3b3 structure, a fac forms a face and a mer have the ligands in meridian position, but for these...

After a ligand bonds to a receptor through intermolecular forces, how is it unbound and what happens to it after it is?

Homework Statement 3 different RGD-containing ligands (including Integrilin) are used to form receptor-ligand complexes, and measured dimerization of ligand-bound receptors as a fuction of temperature in the range 20-40C using a variety of methods. The 3 ligands are cHArGd, cRGD, and...

Naming the complexes with two different types of ligands confuse me. How do you tell which ligand to include first in the name? Which ligand do you write first in the brackets? Thanks for anyhelp

anybody know what the primary mode of ligand substitution for first row octahedral transition metal complexes?
