how do i write the z spin state using the spin state on x or on y?
In summary, "Spin state, base transformation" refers to the process of changing the representation of quantum states in quantum mechanics, particularly for systems characterized by spin, such as electrons. This involves using mathematical transformations to describe states in different bases, which can provide insights into the behavior of quantum systems and facilitate calculations in quantum computing and quantum information theory. The transformation helps in understanding how quantum states evolve and interact under various conditions.

@usai you might not find the responses above completely helpful? :) :)
Seriously, kidding aside, PhysicsForums is generally better at helping people over the hard spots than laying out an entire lecture-equivalent tutorial (better done by textbooks and online course materials). So if you can get hold of a good online explanation of the algebra of the spin operators - several out there and some other poster may chime in with their favorite - and start in on it, come back with a more focused question as soon as you hit a hard spot you'll get better and more helpful answers.
Another way of thinking about it: Suppose you are taking a college-level intro to QM course as part of a physics bachelor's degree (which is about right for this topic and consistent with the I rating you gave the thread). You walk into your professor/TA's office during office hours with this question, the absolute first thing you're going to hear is "How far into the textbook/course notes did you get?". Same thing here, except with the general unstructuredness of the internet layered on top.

FAQ: Spin state, base transformation
What is spin state in chemistry?
Spin state refers to the arrangement of electrons in the orbitals of a molecule or ion, particularly in transition metals. It describes the total spin angular momentum of the electrons, which can affect the chemical and physical properties of the compound. Spin states can be high-spin or low-spin, depending on the distribution of electrons among the available orbitals.
How does spin state affect the properties of a compound?
The spin state of a compound can significantly influence its magnetic, electronic, and structural properties. For example, high-spin states typically result in a larger magnetic moment and can affect the color and reactivity of the compound. Low-spin states, on the other hand, often lead to different geometries and can alter the compound's stability and reactivity.
What is a base transformation in chemistry?
Base transformation in chemistry refers to the process of converting one base (a substance that can accept protons or donate electron pairs) into another. This can involve changing the chemical structure or functional groups of the base to achieve desired properties or reactivity. It is commonly used in organic synthesis and catalysis.
How are spin states determined experimentally?
Spin states can be determined using various spectroscopic techniques such as Electron Paramagnetic Resonance (EPR), Mössbauer spectroscopy, and Magnetic Susceptibility measurements. These techniques provide information about the electronic environment and the distribution of electrons in the compound, allowing scientists to infer the spin state.
What factors influence the spin state of a transition metal complex?
The spin state of a transition metal complex is influenced by several factors, including the nature of the metal ion, the ligand field strength, the geometry of the complex, and the oxidation state of the metal. Ligands that create a strong field (such as cyanide or carbonyl) tend to favor low-spin states, while weak-field ligands (like halides or water) are more likely to result in high-spin states.
